I don't really care about holes in the collection, but there are a few Springsteen albums I rarely, rarely listen to so maybe those, but even then there are some songs on them I do like.
I'm not huge into Savatage, but I love Fight for the Rock.
Unmasked is also so good.
Peter Criss is the only KISS album I don't like anything at all from except Carnival of Souls.
