3. Jeff Buckley - 'Hallelujah'
Leonard Cohen's career was at a low point when he wrote "Hallelujah" in the early Eighties, and his record label had no interest in even releasing the track or the rest of the songs that eventually came out on 1984's Various Positions. The track was a fan favorite, but it didn't receive much love until the Velvet Underground's John Cale created a stripped-down piano version for a 1991 Leonard Cohen tribute album.
Jeff Buckley used Cale's version as the basis for his stunningly beautiful version of the song on his 1994 LP Grace. The track wasn't a single, but after Buckley's tragic death in 1997 the song slowly started to become recognized as a classic.
