I came across this gem while doing a little research on Dr. Luke.

Back in 2008 The Asphalt sued the Daughtry camp for the similarity of his song “Feels Like Tonight”.

Daughtry is being sued by Randy Mazick [The Asphalt] because Mazick alleges that the song “Feels Like Tonight” on the album “Daughtry” is a copy of Mazick’s own song called “Tonight.” The lawsuit says Mazick said his band, The Asphalt, first performed the song in 2005, ahead of Daughtry’s 2006 release. – macworld

According to wikipedia the case was eventually settled out of court.
