wedding songs - alternative

Hi everyone,

FH and I have picked several first dance songs...however, once we think we have it we go to a wedding and the song is that person's first dance song!! I know that we will have the same song as other couples but I really want something unique and special...not something you hear every time you go to a wedding. I really like alternative/rock songs. Does anyone have an suggesstions for me??

Thanks!
