As for your 75-66 list...
8/10
Backstreet Boys - Good pop song. Generic production but nice melodies.
Daughtry - Very boring. A bit better than but very similar to Nickelback. God I just hate soft rock.
Paramore - I've always liked this song.
Lady GaGa - Hard not to enjoy it at least a little bit.
Kings of Leon - Absolutely loved this song until it was played too much on radio. Still give it a nod though.
Taylor Swift - Sweet song. Once again... hard not to like it.
Jordin Sparks - Really good.
Snow Patrol - Nice. Simple.
Cobra Starship - Nope.
The Fray - Very catchy, very good. I know some people hate them but I have a thing for them. "How to Save a Life" is one of the best songs of the last few years.
