There are some bands from the late 70’s and early 80’s whose one or two or three albums never made it to CD, but at least some of their stuff made it to a “best of” a little later. Sometimes that’s what you’re stuck with, although I’ve been known to deconstruct a “best of” album and edit the tags and album art to reflect the original album a song came from. That way I end up with incomplete albums, but that’s better than seeing a “best of” in the album column.
::shudders:: having “best of” in the album sort is almost as bad as having that column blank or “unknown.”
