I'm looking through my CD list, and thanks to buying CDs by Gerling and Endorphin, I've finally filled the gaps in the "G" and "E" directories. To have the whole alphabet, I still need "I", "Q", "Y" an "Z".

Q is easy - I've been meaning to get one or two Queen CDs (Night at the Opera, and the one with the big robot on the cover with We Are the Champions on it). Any suggestions for the other three? (No, I've never really liked Zappa enough to get one of his albums)
