I'm 100% sure those 6 songs are no new studio songs.
They will be the covers, I'm quite sure. I already read somewhere that the Marley cover and Mr. Pitiful is on there, it would only be logical if two other ones are Bob Wills (the whole song was performed, with sssoul!) and Learning The Game. Night Time from Rio will likely be another one. The 6th one is perhaps Hurricane, then.
