I love all the songs, I really do, but Flightless Bird was the one that blew me away. I could listen to that song 24x7.
Supermassive Black H*** by Muse hands down. I've created a ring tone with it for my iphone.
However, I really do like the Paramore songs, especially Decode and I really like the Mute Math song. I also like Tremble for my Beloved song, Eyes on Fire, and Full Moon.
I don't like the prom song at all - ugh! And I don't like the Perry Ferrell song - really cheesy.
