Musicolet is amazing

I have just discovered this app and I think it's probably the best music player I've used. It's fantastic. Seriously, it's small, customizable, custom eq, widgets. I couldn't find a single thing I don't like. The blurred album art effect is also very cool (enabled in settings). Oh and it's free. I am not affiliated with the dev.

One other thing I forgot to add is it has those awesome Full colour notifications
