Naming Convention For Compilations

[Five]

Okay, we all know about the

artistYYYY-MM-DDd1t01.flac
artistYYYY-MM-DDd1t02.flac
...etc

way of naming files, but what about if it's a compilation??? Specifically, what would be the best way to name the tracks for this disc:
http://www.bootlegzone.com/album.php?name=beatvers&section=1

thx in advance

[mgleason007]

beatles_solosd1t1.flac

Just a guess

[Five]

hmm...

maybe

beatles-bvosbd1t01.flac

gotta get that --^ "zero" before the one so it sorts

??

beatles_vosbsam_d1t01.flac
beatles_vosbsam_d1t02.flac
