Woah — first solo news in awhile, not like it’s a bad thing (no offense, G!), but “Hollaback Girl” is going to be included in the upcoming Guitar Hero spinoff, DJ Hero. Thanks to Pocket Lint for the link, I found the video on YouTube that debuted last night. It’s actually featured in the trailer as well mixed with Rick James’ “Give To Me Baby,” and sounds pretty good. The game is scheduled to hit stores in October.
