There are a number of annoying things with that player. Quasar MX cannot read disc number tags so you have to switch to sort by location if you want to listen to albums with multiple disc so they're properly sorted, it doesn't pause automatically when you recieve calls or any other audible notification, you cannot queue music and there are some weird bugs that causes the music to be sorted wrongly. The default media play is even worse So I thought I could use Poweramp or a simliar player but they won't work properly.
