The second disc of this 2-CD set (or single DVD-audio hybrid in some regions) includes material you cannot find on streaming services in high quality. Tracks like “Valerie” (the BBC Radio 1 Live Lounge version that became a hit of its own), “Cupid” (a Sam Cooke cover), “Monkey Man” (a Toots & The Maytals cover), and the acoustic demo of “To Know Him Is To Love Him” are included. The FLAC rip of these tracks is particularly vital, as many YouTube uploads are lossy, compressed abominations.
While the 2007 Deluxe Edition FLAC files are widely shared among enthusiasts, true purists often seek the original European CD pressing (Island Records 173 428-5) to rip themselves. Additionally, a 2020 “Back to Black: 5-Track EP” in high-resolution FLAC (24-bit/96kHz) exists, but for the full album experience with the bonus live material, the 2007 Deluxe Edition remains the definitive digital artifact.
