I have been in need for Springsteen to finally join his bandmember's game.
Bruce isn't a four piece band sadly, which makes it difficult to select songs that blow away people in gameplay and in overall sounding. These songs I've found would probably fit the ticket:
-Born to Run, with the exception of the Big Man's solo, it fits the 4 piece band very well
-Brothers Under the Bridges ('83), one of his quite unheard of songs he blasts people away with a strong guitar and drums.
-Rosalita, the song that is considered true rock in its total essence
-Glory Days, though lacking the Big Man, it features a simple rift and lyrics overall, I'd put this song as that easy song you have to ad.
-Murder Inc, harder rocking, one of Bruce's more guitar oriented songs, a MUST for Rock Band
-Radio Nowhere, harder rocking, though the lyrics aren't his best, it is another song that Rock Band would be smart to feature considering
-Summertime Blues, you'll say wait, that's already on Rock Band. After buying some of the better Who songs, I decided to purchase this aswell. In comparison with Bruce's version, the Who's is slow and doesn't feel as exciting. Imagine now playing the Who's version x4 speed is what you get in springsteen's live covers
This is of course my 2 cents. I have listen to probably 95% of all Bruce's songs and these are the ones I thought fit the gameplay the best. There are songs that should be added to my list if RB had keyboard and horns.
