If I'm like any of the other rockers, I like to download the new DLC the day it comes out and play all of those songs right away, and then I usually like to play the previous weeks stuff (just to get familiar with the newer DLC). Today as I was going threw the 200+ tracks in Rock Band when I though, why isn't their a category called "by date downloaded" or "by date released". Seems like a pretty useful thing to do (probably easy too, but I'm no developer).
If there isn't new ways to find songs in Rock Band 2, I think by the end of the year (500 songs I'm looking at YOU!) we will have a patch to change that, otherwise it will take an unacceptable amount of time to find a song your looking for.
Maybe I'm the only one who has problem with song selection taking to long with our ever growing list of track, but I doubt it. Lets hear how you feel about.
