You get complete construction kits comprised of all the loops, individual beats and riffs for all the instruments used in each hit song. You can manipulate, remix and drop out any instrument to make room so you can play along. This is the ultimate way to learn the drum part or guitar riffs of these great hits.

Classic Rock TrackPak has hits from the '60s and '70s including Aerosmith, The Beatles, Cream, Lynyrd Skynyrd, Tom Petty, Van Halen and ZZ Top. The Modern Rock TrackPak has songs from Alice in Chains, Bllink-182, Incubus, Jet, Maroon5, Nirvana and others. R&B has complete tracks for twelve Motown and Soul artists from James Brown to Marvin Gaye, The Temptations and Aretha Franklin. Hip-Hop has music originally recorded by 50 Cent, Eminem, Ja Rule, Jay-Z, Nelly and Snoop Dog.

These are tracks of audio and not just MIDI data playing cheesy MIDI instruments and they each include songbooks with sheet music notation for reference. At $29.95 each, TrackPaks for GarageBand are available from Hal Leonard through Music Dispatch at 800-637-2852 or www.musicdispatch.com
