Random thought, I think what's going with All Summer Long and American Boy will be a trend for artists in the future. If a popular song isn't available on iTunes, they'll probably have a substitute version available in the store. I bet Kid Rock and Estelle won't be the only ones to have this happen.
Ewww at people buying crappy tribute versions of songs
