Hello, i'm new to this forum so excuse me if a thread regarding this question allready exists. Can anybody please tell me if the isolated bass lines on youtube are the original studio recorded bass lines. Here are some examples: - - - - etc. I've read that the tracks are isolated from a game called Rock Band 2 and i'm always seeing endless debates about whether they are real or not. So i'm wondering if any of you know this for sure, thanks for the reply .
