Audio
You can upload MP3 files of you performing a Beatles cover, an original mix, karaoke, or even a song you did inspired by the Beatles. The important thing here is that the song you upload is yours. Absolutely no copyrighted music. Seriously, none. That would be an enormously bad thing to do because it may cause this otherwise very cool section of theBeatles.org to be shut down and ruin everybody's good time.
