Here's a wonderful question, Which artist has the most number of songs in your collection?
For me & probably many others, it's The Beatles followed closely by Green Day.
Having almost all the albums from exports & customs for both bands is kind of ridiculous but hey, they're worth it. TBH Not all The Beatles songs are exciting but I'm a completionist haha. I played the crap out of both games when they came out & it was the greatest thing to me to find out that I could play them in Rock Band 3 with Pro-Drums. I'm curious to find out what you guys will say!
