Ooo, the Cure are amazing, I thought they went into retirement but they had a new album come out a couple of years ago.

Personally the bands which seem to put me in a very good mood are:

Bruce Springsteen (all time favourite)
The Eagles
Rolling Stones (classic one there)

Never actually listened to the Beatles considering everyone seems to think that they were the most amazing thing ever. I cannot think of anymore at the moment but those three are definitely at the top. Best era of music was the 70's and 80's in my opinion. It is terribly sad that I was not alive to have heard it back then first hand.

My all time fav band is Faith No More, closely followed by ;

Incubus
papa roach
3 doors down
stone sour & many more...
