Rock Band 3 Not Cloud Supported

The only thing that is cloud supported are the game saves. Content cannot be stored on the Cloud. There is no fix for this.

This link will tell you how to import other Rock Band Games into your Rock Band 3. Scores do not transfer over into RB3.

Sorry you used to be able to use you headset as a mic in Rock Band. They changed it in Rock Band 3 for some reason. You can only use a rock band or guitar hero mic on rock band 3. But you can still use it for Rock Band 1,2

Katamari Damacy 1-3. Also Rock Band Blitz and Rock Band 3.

That would be amazing.

Rock Band 3 has something for every genre of music, even Hip-Hop (ex. The Snoop Dogg track pack).

If I were you, I would buy Rock Band 3 as well as the first two Rock Band installments (Rock Band and Rock Band 2), so you can export the tracks from the first two installments. Don't worry about the cost. The first two cost roughly $10 together and $15
to export the songs ($5 [400 MSP] for Rock Band and $10 [800 MSP] for Rock Band 2). You might also consider looking into buying Green Day: Rock Band too.

If you're still skeptical, look online for the 83 default songs on Rock Band 3. Hope this helped.
