Is Toby Keith's party anthem "Red Solo Cup" a ripoff?

Texas hip hop artist Carlton Zeus released a song and video over a year ago called "Sharpie Solo Cup".  His fans are up in arms claiming Toby "cant come up with his own song or video. what a rip-off........."

According to one Twitter comment: "This is too much of a coincidence to not be a copy. Carlton Zeus had the original. If you watch both videos, they both start off at the hotel room door, same lighting and everything. Toby Keith had a higher budget but a horrible song. Carlton Zeus all the way!"

No comment (yet) from Toby's camp.

Here's a video of Carlton addressing the comments.
