We already have confirmation on 22 tracks that will be included with Rock Band 3 this fall.   RockBandAide has posted a screenshot from the International Trailer which show the following tracks in the song selection screen:

• Blood, Sweat, & Tears - Spinning Wheel
• Chicago – 25 or 6 to 4
• Faith No More – Midlife Crisis
• INXS - Need You Tonight
• T.Rex – 20th Century Boy
• YES - Roundabout

Earlier in the month, canadian retailer Gamestop let customers know that by pre-ordering Rock Band 3, they would receive the following tracks as DLC (presumably via a redeemable code):

• Talking Heads – “Burning Down the House”
• Deftones - “My Own Summer”
• New Order – “Blue Monday”

The site does not go into detail about when the tracks will be available – as you recall with Rock Band 2, fans waited for months until the ‘bonus tracks’ were released.   Hopefully these are made available on the same date as the retail release (as in the “All You Need is Love” DLC when Beatles: Rock Band came out).

There is a lot to be excited about with what has been revealed thus far.   “Roundabout” and “25 or 6 to 4” are both 70′s prog-rock classics, “Burning Down the House” was conspicuously absent from last year’s Talking Heads DLC and is destined to be a party favourite.  Here’s the video from 1UP that contains the aforementioned setlist sequence.
