Hal Leonard has released the first four Apple Loop products in their TrackPak series for Garage Band. Each release contains loops for 12 hit songs in a different genre: Classic Rock, Modern Rock, Hip Hop, and R&B.

In addition to loops for individual instruments from each song, each TrackPak comes with full audio tracks for those who like to make their own loops, plus fully mixed GarageBand projects for each song. Every TrackPak also comes with a book containing complete musical notation and guitar tablature for every loop.

TrackPak features professionally produced versions of well-known songs such as Nirvana’s “Smell’s Like Teen Spirit” (Modern Rock), 50 Cent’s “In Da Club” (Hip Hop), The Commodores’ “Brick House” (R&B), and Lynyrd Skynyrd’s “Sweet Home Alabama” (Classic Rock).
