Percussionless songs... I have three albums that come up instantly that are ambient/experimental.. and are on Spotify.
Amon Tobin - Dark Jovian, an EP released for Record Store Day. Inspiration came from binge-watching space exploration movies. Adrastea Contact is a good example.
Hecq - Night Falls. A full-length remastered album. The feeling of going out to a very cold night, clear skyes, frost everywhere. You're wearing pretty much nothing but pj pants and a coat. Everything is beautiful and very very dark. Bending Time is nice.
Odd Nosdam - T r i s h, a little EP. Echoing beatless remnants of a failed album, but very loveful nevertheless. I think I like Olynn.
