Can you transfer youtube audio files to iPod?

What model of iPod are you using? If you are using an iPod Touch, you can download the YouTube app directly from the Apple Store to your device. You can then stream YouTube Music just like you would on your computer or phone, but if you want to download songs for offline playback, you'll have to pay for a YouTube Premium membership.

If you are using an older model of iPod, which is discontinued by Apple, your device will not be able to connect with the current model. Then your device will not be compatible with the current YouTube Music app. But that's not to say you can't play YouTube Music on it, I suggest you use TunePat YouTube Music Converter to download all your favorite songs from YouTube Music in MP3 format and then transfer them to your iPod for playback.
