MTV and Harmonix have added Fall Out Boy song "I Don't Care" and Hinder track "Use Me" to Rock Band.
Each costs 80 Microsoft Points (GBP 0.68 / EUR 0.96) to download. And that's cheaper than a can of diet Cherry Coke.
The duo arrives alongside the known-about Presidents of the United States of America song pack, which includes "Ladybug", "Feather Pluck'n" and "Dune Buggy".
These can be bought individually for 160 MS Points (GBP 1.36 / EUR 1.92), or for 440 MS Points (GBP 3.74 / EUR 5.28) as a bundle.
All of that is less surprising than the recently-announced European date for Rock Band 2, which will be released as a timed-exclusive for Xbox 360 on 21st November. Instrument bundles will go on sale from early December.
And remember, downloadable content is compatible with both Rock Band 1 and Rock Band 2.
