FLAC is a bit-perfect copy of the original CD data. For a band like Mötley Crüe, whose production style relied heavily on "big" room sounds and layers of backing vocals, listening in FLAC allows the listener to hear the separation in "Kickstart My Heart" or the haunting atmospheric depth of "Home Sweet Home" that MP3s simply strip away. The Tracklist: A High-Octane Journey

Take a song like "Dr. Feelgood." Recorded in 1989, it is widely considered one of the best-produced hard rock albums of all time. The low-end thump of Nikki Sixx’s bass and the snap of Tommy Lee’s drums are distinct and separated in the mix. In standard MP3 format (especially lower bitrates), the compression algorithms tend to "smear" these frequencies together, resulting in a flatter, less dynamic sound.
