Indeed. I'd love an app that allowed me to download songs (from torrent etc.) - the desired version, quality, ID3 tags and so on without issues. That would be a big improvement on most music services (streaming and buying). However, this looks to mainly be a low-quality Spotify alternative, so...
You may be interested in soulseek[0]. I use it to search for more obscure music and the results include the bitrate/format. There's also a watchlist function in case you can't find something so you can keep searching in the background. Afterwards I use beets[1] to autotag everything with musicbrains and move it to my library folder, and it usually works. The downside is it isn't a streaming service so you have to find some way to listen remotely. I use Plex[2] for this and haven't had any issues. Also since it's P2P there's a general expectation that you also share things with other people, so you'd have to be prepared for that.
