If you're talking about Beatles covers, there are countless compilation.

If you're talking about songs they did for other artists, there is a comp called THE SONGS THE BEATLES GAVE AWAY. It makes for interesting listening, because these songs were just as good, but perhaps they were given a tip on the wonders of publishing, or simple wanted to create for the sake of helping out friends and other artists.
