Without further ado we can tell you that the tracks, which are all original master recordings, are:
Sin Wagon by the Dixie Chicks
Still Alive by GLaDOS and Jonathan Coulton
Here Comes Your Man by The Pixies
Losing My Religion by R.E.M.
Pride and Joy by Stevie Ray Vaughan
That brings the number of songs available in the Rock Band Unplugged music store to 19.
“This latest update brings another wide variety of musical genres to the game, including country music trio The Dixie Chicks, electric blues guitarist Stevie Ray Vaughan and alternative rock groups R.E.M. and The Pixies,” said a statement by Harmonix and MTV Games.
Rock Band Unplugged features the first in-game store for downloadable content on the PSP system in the North American and European markets.
