Jammit - the ultimate play along app and music platform for aspiring musicians - has recently added more than a dozen classic tracks from heavy metal pioneers JUDAS PRIEST, MEGADETH and prog-metal legends DREAM THEATER to its vast music library. The Jammit catalog of artists ranges from NIRVANA and PANTERA to BOSTON, DEEP PURPLE, FOO FIGHTERS along with the modern metal of MASTODON and FIVE FINGER DEATH PUNCH with hundreds more across multiple genres.

Highlights of this latest catalog expansion include Judas Priest’s seminal metal anthem 'You’ve Got Another Thing Comin’', Megadeth’s 'Youthanasia' and Dream Theater’s 7-part epic 'A Change Of Seasons'. In addition, Jammit’s “Weekly Priest” promotion promises a new Judas Priest track available every Wednesday for a limited time.

Jammit is the only app in the world that gives users an all-access pass to live that rock star experience - the power to play on the original hit recordings, right along with the original artists. Available for iPad, iPhone, iPod Touch, and Mac and Windows desktop (with an Android version in development), the free Jammit app download allows musicians of all skill levels to not only play over original master recordings but to slow them down or speed them up. With Jammit, users can actually play along to the isolated tracks recorded by their heroes without having to hear all of the other instruments simultaneously. It's a groundbreaking and game-changing concept for guitarists, bassists, drummers, keyboardists and singers everywhere.

Jammit debuted soon after being named the best iOS app at the MacWorld Expo by Mac | Life magazine. Jammit has since expanded both its platform compatibility and its music catalog: Jammit’s diverse selection of songs spans the history of popular music, with nearly 2,000 individual tracks now available from over 200 artists spanning all genres of rock music, as well as Country, Pop and Blues.

Jammit’s extensive library of original multi-track recordings plugs users into the actual recording sessions, from rock classics to the latest releases. Along with its unprecedented access to original recordings from some of rock’s most recognizable and innovative artists, Jammit offers a variety of features that accelerate the process of learning new songs. Tracks are rated for difficulty (on a 1-5 scale) and individually priced for each instrument. Some of the most difficult and most popular tracks come from the intricate prog-rock of YES, RUSH and Dream Theater.

Users can click on any part of the screen to isolate that one bar that they're trying to master. There's a timing reference added so that the rhythm is completely correct, and in addition to offering standard musical notation for every song, transcriptions for guitar and bass can be viewed in the more familiar tablature format.

“Drummers can play along to Neal Peart. Guitar players have the opportunity to hone in on that gnarly John Petrucci solo and then take it on. It's the ultimate 21st century stage,” says Jammit founder and renowned music producer Scott Humphrey (Rob Zombie, Mötley Crüe, Fuel).

Dream Theater:

'A Change Of Seasons' (Pt. I)

'A Change Of Seasons' (Pt. II, III)
