DJ Hero and Guitar Hero fans planning to rock out this weekend for the 4th of July are in for a treat as Activision has announced the release of two new track packs for the games with songs from Lady Gaga, Rihanna, Maroon 5 and more.

The DJ Hero Dance Party Mix Pack contains three new mixes to add to your music library including Lady Gaga’s “Poker Face” mixed with “Girls On Film” by Duran Duran, Pussycat Dolls’ “Buttons” beat juggle and Rihanna’s “S.O.S.” beat juggle. The DJ Hero Dance Party Mix Pack will be available on Xbox 360 for 640 Microsoft Points and the PS3 for $7.99.  All mixes will be released as downloadable singles for Wii for 300 Wii Points each.

The Guitar Hero Pop 1 Track Pack also features three new songs from hit pop artists including Lady Gaga’s club anthem, “Just Dance,” Maroon 5′s hit single, “This Love” and the Synthpop hit, “Fireflies,” by Owl City. The Guitar Hero Pop 1 Track Pack will be available for the Xbox 360 for 440 Microsoft Points, the PS3 for $5.49 and the Wii for 550 Wii Points.vAll songs in the track pack will additionally be released as downloadable singles for the Xbox 360 for 160 Microsoft Points, the PS3 for $1.99 and the Wii for 200 Wii Points each.

Activision’s got a great idea by releasing new track packs for both DJ Hero and Guitar Hero right before Independence Day, but if you really think about it, it’s just another way to make more money for themselves, something they’re extremely great at. But still, you can’t deny that they are giving back to their loyal fan base with great new songs to download and for a reasonable price.

Both track packs are available today, so pull out those credit cards and get ready to jam out this weekend for the 4th of July.
