I liked Bittersweet the best out of the Fuel songs.. Seriously.. it IS the best Fuel song.
They have a lot of good ones besides just Shimmer and Hemhorrage, though.
I went to a concert at Janus Landing that was Virgos Merlot (now Virgos and an emo band instead of alternative/grunge) and Buckcherry (still around.. bigger than Fuel now) opening for Fuel. It was cool cause' it was a smaller concert, yet the bands were really good. Fuel is really good live.
Now go listen to Bittersweet.. the BEST fuel song.
EDIT: From Wikipedia:
Fuel had already laid down the instrumental tracks for their fourth album and soon started auditioning singers so the band could move forward. Abercrombie and Bell took notice of American Idol contestant Chris Daughtry, after he performed "Hemorrhage (In My Hands)" on the show and the single shot up to the Top 10 download list on iTunes and stayed there for a number of days. This also sparked interest in other Fuel songs, which began to appear the Top 100 download chart on iTunes. On March 3, 2006, judge Randy Jackson stated in an interview that Daughtry had been offered the opportunity to become Fuel's new lead singer.[1] Fuel confirmed their interest on their official website. On May 11, 2006, Abercrombie and Bell appeared on the TV show Extra to officially offer Daughtry the job.[2]
