Spotify is quite good but in my opinion i think that the suggestions mech built into spotify is brutal! Crap being honest! If i listen to chill, i then sometimes get rock recommended etc. Where apple i heard is suppose to be really good. I never tried, i still use spotify cause it has a huge library and is good apart from the suggestions mech.
Spotify has so much data but they dont use all of it to their advantage? If i was them i would add so many features matching BPMS, Artists you listen too etc. <-- As far as i can see now.. They dont have such systems in place. Perhaps apple does?
Apple Music for me cuz it got better sound quality than Spotify. I'm working at a gas station, got no WiFi and the internet connection is shit most of the time. So I downloaded all songs from AM library with Tunelf Audio Converter and it just works so perfectly. I don't even have to take my phone to work. I put them into my super old mp3 and my songs still sound sweet.
