Why YSK: Spotify forces you either to pay, listen to ads or to find unofficial, potentially dangerous versions to use it. It's better to find a free alternative, both for your wallet and for your peace of mind.
AFAIK ViMusic is no longer being actively maintained. An similar app which is InnerTune although I'm experiencing some weird glitches during search (unable to subscribe to an artist and playlist tab remains empty for every search).
It's true its last update was in November, but the dev(s) still monitor and reply in the issues tab. Most important, the app works flawlessly.
The project still seems alive to me, but if you prefer innertune by all means go with that! I followed it for a bit (when it was still called "Music") and it's a great app
