It's not the fault of "CDDB" - TR is using the database of FreeDB and it most certainly contains full information for every compilation album I have in my collection. Some of the entries had artist and title reversed, but I made sure to submit corrections for everything I owned. However...

I believe Tony was talking about the data from AllMusic. For compilations it doesn't include the name of the artist (at least for the few albums I pulled up over the past week). What it does include are the names of the composers/writers/lyricists (credit) for the tracks.
