What, like Pandora, Spotify, etc is out there that I could add music I have on my phone/etc?
I've been using one of the Pandora services, but I've been getting a little annoyed with the stations (which I presume I would get the same annoyance from other services, too). So I'd like to be able to create a station and add songs that I own and that wouldn't normally be in that station. (And I know you can add artists to the stations, but some artists only have a few songs I like, and I surely don't want the station inundated with similar artists of the music I don't like. Shudder the thought, 😬 ).
If you like what's on offer by Spotify, there's a free alternative that I like called Spotube. It uses your Spotify account for recommendations but then uses YouTube's (and YouTube Music's) backend to get the songs. You can also change the backend use a Piped instance instead of YouTube.
