John Peel's Festive 50 was an end-of-year chart compiled based on the votes of the Radio 1 DJ's listeners. It was first broadcast in 1976 and thereafter was broadcast almost every year. It was always an interesting snapshot of the year in music, though it leaned more heavily on white boys with guitars than did Peel's own taste. I've noticed a few people making Spotify playlists of old Festive 50 lists. So far I've found 1978, 1982 and 1988. I thought I'd sift through Spotify myself and see what the online music service could do for Peel's 1990s lists. A couple of the 90s lists were unusual - Peel didn't broadcast the 1991 list until 1993 and he broadcast only the top 31 tracks from the 1997 list, even though all 50 were chosen.
Anyway, Spotify did ok. The most tracks I found were from 1990 - 38 of the 50 - and I found the fewest, 23 tracks, for the 1997 and 1999 lists. The playlists are below. You'll need to install Spotify on your computer to listen to them and some tracks may be unavailable in your part of the world.
