How to Put Music From YouTube on a USB Stick for Your Car

You've found the songs you love on YouTube and want them in the car. Newer cars can play music from a phone, but many older stereos only take a USB stick or a CD, and they're picky about both. A stick that works fine on your computer can show "No file" or "Unsupported" in the car. Usually the problem is how the stick was prepared or what kind of files are on it, and both are easy to fix.

TL;DR: Use a USB stick of 32 GB or less, formatted as FAT32. Save the songs as MP3 and keep the cover pictures small or turn them off. Copy whole folders, with numbers at the start of the file names, so they play in order. On a Mac, remove the hidden files the Mac leaves on the stick. If the car only has a CD player, burn an MP3 CD or an ordinary audio CD.

What an Older Car Stereo Can Play

MP3 is the one format that plays in practically every car stereo with a USB port or an MP3 CD player. Some stereos also play WMA or AAC (the format behind M4A files), and newer ones may play FLAC, but you can't count on it. If you're not sure what yours supports, MP3 is the safe choice.

Quality isn't a worry here. An MP3 at 192 kbps sounds just as good as anything else through car speakers with road noise in the background. You don't need 320 kbps, and our post on why 320 kbps from YouTube isn't better explains why.

Pick and Prepare the USB Stick

Older stereos usually read only sticks formatted as FAT32, and many have trouble with sticks bigger than 32 GB. Some ignore a large stick completely, others only see part of it. A 16 or 32 GB stick holds several thousand songs, which is more than enough for the car.

New sticks of 64 GB and more usually come formatted as exFAT, which many older stereos can't read. A stick of 32 GB or smaller usually comes formatted as FAT32. If you need to format it yourself, remember that this erases everything on the stick.

• On Windows, open File Explorer, right-click the stick, choose Format, pick FAT32 as the file system and click Start. Older versions of Windows offer FAT32 only for sticks up to 32 GB. Recent Windows 11 updates offer it for bigger sticks too, but an older stereo may still not read them.
• On a Mac, open Disk Utility, select the stick and click Erase. Choose MS-DOS (FAT) as the format and Master Boot Record as the scheme. If you don't see the scheme option, choose View > Show All Devices and select the stick itself, not the volume under it.

Get Your Music as MP3 Files

YouTube to MP3 Converter saves songs as MP3 at 192 kbps unless you've changed it, and that's exactly what an older stereo wants. If you switched to Original M4A at some point, switch back before you start: open Preferences, go to the Audio output tab, choose Convert to and select MP3. M4A plays on computers and phones but often not in an older car.

The MP3 files are saved at 44.1 kHz, the same sample rate as a music CD. A few older stereos are fussy about other rates, but 44.1 kHz is the one they all play. The program also writes the song title and artist into each file in a way older stereos understand, so the names show up on the display instead of "Track 01".

Cover art is the one thing to watch. The program puts the video's picture into each file as album art. Most older stereos simply ignore it, but some stumble on large pictures: they skip the song, play it with a long delay or show an error. If that happens, open Preferences, go to the Tags tab and set Artwork to no. If your stereo does show covers, choose cropped to 480x480 instead, which keeps the picture small.

For whole playlists, two settings help. On the same Audio output tab, turn on add number to filename (if video is part of playlist), so every song starts with its place in the playlist. And turn on place in subfolder named as playlist title, so each playlist lands in its own folder. Our guide on downloading a YouTube Music playlist walks through the rest.

Already have the songs in the Music app or iTunes? Our guide on copying an iTunes library to a USB drive covers that case.

Keep the Songs in the Right Order

Many car stereos don't sort songs by name. They play them in the order the files were copied to the stick. If you drag songs over one by one, or in a few batches, the order in the car can come out mixed up.

Two things fix this on most stereos: numbers at the start of each file name, and copying each folder onto the stick all at once. Keep the folder layout simple: one folder per playlist or album, right at the top of the stick, with no folders inside folders. Some stereos also have a limit on how many files or folders they can show, so if a few songs seem to be missing, the stereo's manual will tell you the limit.

It's safer to download the songs to your computer first and copy the finished folder to the stick afterwards, rather than downloading straight to the stick.

Using a Mac? Clear Out the Hidden Files

When you copy files to a USB stick from a Mac, the Mac may quietly add small hidden files next to your songs. Each one starts with a dot and an underscore, like ._My Song.mp3. You never see these files on the Mac, but the car stereo does. It tries to play them and shows them as broken tracks or "unsupported file" between your songs.

To remove them, open Terminal (it's in the Utilities folder inside Applications), type the line below with your stick's name at the end, and press Return. Then eject the stick as usual.

dot_clean -m /Volumes/USB

Replace USB with the name your stick has in Finder. If the name has a space, put it in quotes, like "/Volumes/MY MUSIC". The command only deletes those hidden extra files, not your songs. If you'd rather not use Terminal, nothing bad happens if you leave them. The stereo will just skip them or complain about them.

Only a CD Player in the Car?

Many CD players from the mid-2000s onward also play MP3 CDs. An MP3 CD is a normal blank CD-R with MP3 files on it, and it holds about 150 songs instead of the 74 minutes of an ordinary audio CD. Look for "MP3" printed on the stereo or in its manual.

If the player is older than that, burn an ordinary audio CD. It plays in any CD player but holds only about 18 to 20 songs.

On a Mac, add the songs to a playlist in the Music app, insert a blank CD, select the playlist and choose File > Burn Playlist to Disc. Pick MP3 CD or Audio CD. For an MP3 CD, all songs in the playlist must already be MP3 files. On Windows, Windows Media Player Legacy can burn both kinds from its Burn tab. On newer PCs it may not be installed, but you can add it in Windows Settings as an optional feature.

The Bottom Line

Older car stereos are fussy, but what they want is simple: MP3 files on a FAT32 stick of 32 GB or less, copied as whole folders with numbered names. Mac users should clear the hidden files before ejecting. If there's only a CD player, an MP3 CD fits a whole playlist, and an audio CD plays anywhere. Set this up once, and the next playlist takes just a few minutes.
