Boy oh boy do we have a once in a lifetime music deal for you, one that'll change your life for the better and make your tummy rumble (but in a good way). Activision has just placed every single Guitar Hero track (from GH, GHII and GHIII) on iTunes for you to purchase dubbed Guitar Hero Essentials. Go ahead, try and tell yourself that you can live without the melodic sound of Metallica, RATM, Pearl Jam or Aerosmith. Try and tell yourself that you don't need to purchase these tracks for when you are away from your 360 and can't play Guitar Hero. Just try and tell yourself that you don't need any of the 1200+ master rock tracks over at the Essentials iTunes store. You can't, because you need this music. You need to purchase it and you need to browse the list. And for a limited time, iTunes will organize the tracks according to genre, theme and game they came from and we'll also throw in a FREE (yes, we said free) air guitar with any track purchase. Hurry, this offer is limited ... call now!
