I’m bored, so here’s some songs I would recommend to people trying out lying on the floor for an excessive amount of time (in no particular order)
1:
https://m.youtube.com/watch?v=BLnDVDYJx0Q&t=10s a compilation made specifically for this purpose. Not the best for me, but it works well enough and might be better for you.
2:
https://m.youtube.com/watch?v=XBUiFHxCGyQ&t=19s an Undertale song made in the context of lying on the floor. Empties your head, but it can get boring quickly.
3:
https://m.youtube.com/watch?v=gFekUBAFbc8&t=78s YouTube recommended this to me for literally no reason. Nice melody and instrumentation, plus nighttime sounds such as crickets to empty your head.
4:
https://m.youtube.com/watch?v=1EDfYW55XoI&t=48s A compilation of Undertale and Deltarune songs (plus remixes and covers) that really sent my record skyrocketing to half an hour longer than before.
