DH got me into them. My favorites are the ones they play on the radio (They have been playing "see the world" and "how we operate" for a while now up here) but I just put the album Bring it On on my iPod. They are so talented. I have to delve more into their music- I tend to listen to the same dozen or so songs (as it seems to go with some bands...)
I highly recommend the song "Make No Sound" from the Bring it On album.
