I not of fan of having to pay for downloadable content but at $6.25 and 650,000 sold I can see why more companies seem to be getting in on the action.  The +$4,069,000 that it has made so far for that content is probably equivalent to an extra 135,000 copies of the game sold.

"Apparently some of you are not sufficiently outraged at paying $6.25 for three new Guitar Hero II songs. Activision announced today that 2 million individual tracks have been downloaded via over 650,000 downloadable Xbox Live packs. The number includes 50,000 downloads for the recent My Chemical Romance pack in its first week of availability and 300,000 sales for the three original Guitar Hero packs through early July.

Activision also used the opportunity to talk up the impending release of Guitar Hero 3 and its "vast array of downloadable content including songs from some of the most popular European bands." Do we smell an ABBA song pack in the works? We can only hope and pray."

eh, realistically, $6 isn't bad for 3 GH songs.

It would cost $3 to buy the actual songs off iTunes...so an additional dollar for each song, for the ability to "play" the songs on varying difficulties, guitar and bass...sounds fair enough to me.

It does add up for each 3 song pack though...

sounds good, never played these games though and I thought playing on my real gutars was expencive :)
