[...]cuz there are sooooo many great songs out there.
Could be. Nevertheless there is one song I can declare to be my favourite song with a clear conscience:
Tool - "Wings for Marie (Pt.2) <img src="/ubbthreads/images/graemlins/up.gif" alt="" />
Damn, I guess there is no song I heard more often... and that's notable, cuz it was publicized in 2006. <img src="/ubbthreads/images/graemlins/exclamation.gif" alt="" />
