Jimmy Buffett IIRC is the only artist to exclusively re-record tracks for Rock Band. I thought that was pretty cool of him.
But personally, I can only play Margaritaville, Cheeseburger in Paradise and Volcano for so long before I want some more.
Continuing the list of the big 8 always played at his concerts,
Changes in Latitude, Changes in Attitude
Son of a Son of a Sailor
One Particular Harbour
I wouldn't mind going for all the main songs, plus some extras, but Jimmy Buffett is a busy guy.
So, all those in favour HMX should get in talks with Mr. Buffett for more re-recorded songs, sign off in this here thread! Suggest other songs you think would be suited for Rock Band!
