Now That's What I Call Music! is a long-running British pop music compilation album since 9th November 1983. The 64th regular numbered edition was released on 24th July 2006 which was the last edition available via cassette tape, where only a limited amount of them was sold due to the fact that they were becoming obsolete. Unfortunately, there are no traces of Now 64 in its cassette format, not even on Ebay or Gumtree; The CD version of it is more common than the cassette copies. The tracklist kicks off with Gnarls Barkley's Crazy, ending with Girls Aloud's Whole Lotta History.
