How many GCH songs had other people singing the hooks? Not to mention how many rap songs have someone else singing the chorus? I could name a million. Just because Lil Wayne isn't singing the hook doesn't mean it's not his song, or that it's not his melody.
Travis is a huge, self-righteous d b, but this song is built for the mainstream. Really catchy and relatively harmless. I'll take the edited version with "frickin" any day.
