What I heard....3/8/09

Again, not much time to listen to anything today. Heard some of ABC's greatest hits album. Kinda forgot how good their songs were. (For some inexplicable reason, I always think of Maya when I hear ABC, which is odd: I don't remember listening to them THAT much together in college. I think it's more of a "sound" or feel that does so.) But what I noticed was that the first 80% of the songs were great, and then the last two or three fell off. Why do GH collections do that......?
