The rock band Chicago has been doing some damn good albums over the years, each numbered differently and featuring a number of classics to rock out to.  But the band never really made its way into the video game world…until now, at least.

Harmonix has announced that it will be launching a three-pack of Chicago songs for both Rock Band 3 and Rock Band Blitz this Tuesday, October 23rd.  The pack will run you $5.49 (or 440 Microsoft points), or you can buy the songs individually for $1.99 (160 Microsoft points) apiece.  They're available for both Xbox 360 and PlayStation 3, and if you have Rock Band 3 for Wii, you can buy them on the eShop as well.

The songs are: "Make Me Smile", "Feelin' Stronger Every Day" and "If You Leave Me Now".  It should be noted that for "Make Me Smile", optional pro guitar/bass expansion is available for a buck more.  All three songs automatically come with keyboard support.

We're a little sad that "25, Or 6 To 4" didn't make it, but there's always time to bring those in with a new pack.

Rock Band 3 and Rock Band Blitz are available now.
