Three shots of Nirvana and a four-pack of Foo Fighters grace the Rock Band Music Store next week, with Joan Jett and the Blackheart's "Fake Friends" this week's sole non Nirvana-related track.

For those of you who prefer Dave Grohl stick to drumming, Nirvana's "About a Girl," "School," and "Blew" will keep him quietly hitting the skins. Those of you wishing for a more pronounced Grohl presence should be pleased with "Best of You," "The Pretender," "Wheels," and "Word Forward" from the Foo Fighters.

If you prefer a more portable Rock Band experience, there's always Bullet For My Valentine's "Waking the Demon" and System of a Down's "Toxicity" for Rock Band Unplugged on the PSP, both of which contain zero Grohl-levels.

Available on Xbox 360 and Wii (Nov. 3) and PlayStation 3 system (Nov. 5):

Setting The Flobots aside for a moment, both The Raconteurs and Electric Six make their Rock Band debut next week, with the former delivering "Dance Epidemic," "I Don't Like You," and the every enjoyable "Gay Bar," and the latter mixing things up with "Many Shades of Black," "Salute Your Solution," and "Steady, As She Goes."

The personal irony of Alanis Morissette's "Ironic" and "Head Over Feet" being added next week is something I am not prepared to explain. Suffice it to say that it is indeed ironic, and not in the Alanis way.

And then we have The Flobots. "Handlebars" has been playing over and over again in my head for the past 2 hours now. I figure this will last for another year. Then maybe Guitar Hero will add it.

All of that, plus new songs from Rush and Green Day for Rock Band Unplugged for the PSP, next week in the Rock Band Music Store.

The store lets you sort all of the games' music by a selection of categories, view original album art for the masters recordings, listen to song previews and check out some extended information about specific songs, like the difficulty rating for each instrument.

We had a chance to check it out in Harmonix suite during the Game Developers Conference earlier this year and were pretty impressed. The menu allowed you to sort by artist, song, genre, album, pack and the difficulty of the song.

Selecting the Music Store from the main menu brings you to a slick interface that allows you to quickly look at new releases, a list of songs available for purchase, song packs and, eventually, entire albums for sale. The front page of the Rock Band Store will also include a sizable box that can show off cover art for the latest album, pack or song and an place where Harmonix can add a message to gamers.

Hopping into the list of songs, gamers can quickly sort by a number of options. When a song is selected on the list, located on the right side of the screen, box art for the music swings down on the left side. It can also show the album name, genre, year it was released and other information.

Hopping into an actual song will bring up an option to preview a snippet of the music as well as a break down of the song's difficulty for each instrument. It will also include a listing of which DLC pack the song is part of.

When Mark and I checked it out at GDC we were very impressed with what we saw, the store will not only help gamers sort through what is increasingly becoming an unmanageable selection of songs, it also looked really damn neat.
