" @Blueprint12 said:" ... and some others I can't remember off the top of my head)... "*cough* Ten, and Backspacer *cough* JK. I'll accept that not everyone would want those entire albums. Those people are wrong though! They're great, dammit! :P "
I'll give you Ten (despite I only have half the album on Rock Band lol), that's a classic ;) But Backspacker is probably more of a fan favorite haha (which isn't a bad thing btw, you enjoy the album at least).
Basically the landmark/classic albums on Rock Band are the must haves...this one might be more of a must have than Axis: Bold as Love but I found that album to be one of the best DLC that came out this year, especially knowing that not much came out during the spring time.
