How does RB organize Album Artist tags for compilations?

[anonamoth]

i just installed RB on my ipod classic. i normally search my library using the Album Artist tags, however, using itunes, the AA tags for all compilations are left empty. it seems this causes RB to list every artist from all compilations in the AA database menu. does this mean i need to fill the Album Artist tags for all compilations with, for example, "Compilations"?

when searching the Album Artist database - it seems to me it would make more sense to NOT list all the artists for which the Album Artist tag is empty/blank. otherwise, you might as well just search the Artists database, no?
