My own playlists (don't wanna be annoying and advertise them rn) but also a few of those official Spotify indie playlists are great for discovering great new indie songs. A lot of small artists in there that you wouldn't find otherwise:D

Here's a link to one of them (I hope it works): https://open.spotify.com/playlist/37i9dQZF1DXdbXrPNafg9d?si=dk9YuhYvS0udyqsc5R6rvw&pi=kcVmqlzCTMWDa

my 'liked' playlist goes hard af, but also soft, weird too.

My go-to is just “my radio” on Apple Music because it plays a large variety of hits and deep cuts of music in my library / that I like while sprinkling in new and old stuff that I don’t have or haven’t heard. I’ve discovered so many great songs and artists over the years by just asking Siri to “play some music” it’s effectively endless good music that can be switched up any time if I want a different vibe by simply re-asking the same question or saying “play something different”.

Otherwise a solid go-to for me is the lofi beats to study to radio and many of its sub-specialties like lofi synthwave or lofi jazz or even lofi christmas.

I once followed my feverish muse into making what I supposed is a Skye Agents of SHIELD/Tom Branson ship playlist

Youtube. I just watch YouTube.

Radio Paradise have a few streams. Personal favourites are the Rock Mix and for lounging around, reading etc. the Mellow Mix. If you want something a little different then the Global Mix might suit you.
For general day to day listening then the Main Mix covers just about everything. For me personally, I find there's too much Beatles and Reggae. I can't stand them. But YMMV.

Although Spotify has some excellent prog playlists, that sodding AI thing pisses me right off (although there may be a way to get rid of that, I've got to try it out) I have Amazon Prime so their music service is a bit of a no brainer as it's cheaper. Not sure if I can tell the difference in audio quality. At 67 and a lifetime of British Army (I was in the Artillery man, play it LOUD!) and working with rock bands, my ears are probably not up to the finer points.
For rock and prog 24/7 then Morow is your friend.

I really like the radio show Beats In Space, it’s on Apple Music now but they have a lot of years of shows on their website — go back to like 2020 — https://beatsinspace.net/playlists/

Mostly electrónica and dance music but very eclectic

While working: battleofthebits radio

They contain 8-bit style music, very neat as a background music while doing other work.

While biking: auto generated spotify playlists.

I really like the different musics Spotify reccomends based on what I previously listen

My own playlists and the discover weekly. Occasionally I use release radar or one of the pre-made ones that do a specific genre.
