I'm currently getting through the free subs. I tried Spotify and didn't like it. YouTube Music was fine, but would sometimes stop playing and not restart on its own. I'm currently on Amazon Music. It has three months free sub, while other services have only one, but it's so bad. The recommendations are all complete miss. It's unusable for me. Even Deezer was a better experience. I'm still yet to try Apple Music and Tidal. Are they better?
I don't listen to music all that much and I feel like it's mostly due to discovery issues. I try to feed the apps the info about my taste, but they don't seem to comprehend. :/
I’ve had no luck with any app in particular over extended periods of time. Spotify has been good, but will occasionally only recommend me stuff I’ve heard a million times for a few weeks straight. My best luck has been following music reviewing sites, or going through playlists featuring artists I like on spotify. This is best with smaller bands, there are less generic playlists with them. Finally, my best bet for finding new music from small artists is simply browsing bandcamp. I’ve found many great artists who aren’t on spotify, and many who are.
As a metalhead, I’m a fan of angry metal guy, as far as reviewers go. RABM on reddit is good too.
