my dear friends, wait no longer. [behold!]
enya's carribean blue (1991) [wikipedia], the first few intro bars, looped for ten minutes.
if you find yourself disappointed upon arriving it's conclusion, i highly recommend downloading the file and using mplayer . run from the command line you can use the left bracket key to slow it down. 0.83x really lands. but you'll still likely be sad when it ends.
 [wikipedia]. you can also use mpv with the --audio-pitch-correction=no option. or maybe i should just upload the slow version. 
 update: [ok here] via ffmpeg -i input.mp3 -af atempo=0.83 output.mp3
