I want to get off spotify, but I want a way to discover new music, and be notified of new music from bands I listen to. I don't want ads, and I'm fine with piracy so long it is a relatively painless experience. Something like stremio but for music.
My dream service would be one that could recommend music based on a given song, and provide details about the artist and things. And even better version would have an API I could tap into so I could connect the service to music assistant. Hell I'll make a (mostly) locally hosted version of the spotify dj if I can.
I've been sort of a bleeding-edge (ie very new) music enjoyer. Most artists release music to streaming services on Thursdays at midnight, because midnight is Friday and Friday is the start of the weekend when people get off work.
On Thursday night, I look at the link below to see a list of new albums which were released and then I search for them on youtube music. I just try out different new albums. You can also click the month button to see the most popular albums of each month.

You're pretty much describing 'last.fm'? It tracks the music you listen to in a similar way to spotify. You can install the plugin in your media player and then the website records the names of the files you play and recommends you similar music. Some people says that it's an invasion of privacy and there's an alternative site called 'librefm'.
