Suggestion: Give users a way to download their Rockband 2 songs without the use of Rockband 3. I don't have Rockband 3, and while it seems like a fun game, the only songs I have access to currently are Rockband 1 songs (my Lego Rockband had a faulty and irretrievable code and Rockband 2 has no method) and the countless DLC's I purchased for that game.
I think the brilliance of Blitz is the ability to reuse DLC purchased for a different title. Blitz does not play like Rockband, nor should it. The use of content purchased for other titles makes this game very interesting and I applaud the use.
Suggestion: A playlist mode similar to that in the previous rockbands. Playing a few songs back to back would be quite neat, or sending a friend a playlist they can attempt to score against. Coins do not need to be granted for these unless a method to remove exploitation could be easily found.
Thank you for your time. -Adam
