Pretty cool things I've found over time. rekt.network offers some cyberpunk vibes with a few different stations to choose from. Nightwave plaza is, as you might expect, nightwave. Soma FM offers a variety of channels with different genres and vibes. Lofi Girl is restricted to youtube, and therefore has ads, but the others are ad-free.

TuneIn- Note that these guys will try to sell you a premium subscription, allegedly its full of ads (I wouldn't know, I use ublock) but there's a hardcore station on here that I can't find anywhere else
