Original of "T-Pain - Fan Call"! pleaseeeeeeeeeee helppppppp

I'm looking for the original version of the T-pain - Fan Call from his mixtape "Back At IT"! Please can you help me ? You can have a preview of the song on this page Here

You're talking about the music on the background? Why do you think it's a cover?

Yep the background music. I think it's a cover because he made covers on all the tracks of "Back at it". That's why... Someone else can confirm that it's not a cover????
