Apparently #TuneTuesday is a thing over here on Mastodon? Anyways I'm always happy to share and receive music recommendations.
An all-timer for me is this song by Rachel Grimes, an incredible pianist & composer who was a part of the chamber ensemble Rachel's (not named after her 😅 ). This song is such an interesting listen, but it demands good speakers/headphones to really get the most out of it.
If you're interested, there are quite a few music hashtag thingies going on here.
@neurothing and others have compiled a database that collates most (or all?) hashtags and if applicable days of the week:

Have fun! 🌞
PS: There are also hashtags like "nowplaying" or "music" for any type of music on any day. Just in case you don't know, on Mastodon you can follow hashtags, not just accounts.
