THE SOUND OF MUSIC
The JDO Playlist has been the soundtrack to bad ideas since the original JDO, and has evolved quite a bit over the years.
As of today (literally today, I checked), it has this many songs and it is this long (Apple Music or Spotify)
You will get your original wager for one of these being right, and double your wager if they're both right (somehow). +/- 25 and an hour gimmie
THE ANSWER IS...
Apple Music: 552 songs, 36 hours and 13 minutes
Spotify: 540 songs, 35 hours and 16 minutes
I don't know why they're different.
