"You dont know what "- (you've been missing?)

Hello,
I listen to kroq 106.7 on 7/30/07 at 2:04 p.m. they played an older song, not sure but it's very fast paced and the lyrics go something like this, " You don't know what you've been missing", it's kind of hard to understand, I tried to check playlists for this day, but there are none. can you help identify the song and artist? Thanks to anyone that will help. Bree.

Try "Your Own Disaster" by Taking Back Sunday or My Chemical Romance

And I don't think that you know
what you've been missing
cause I don't think that you know
what you've been missing
