So many designers remix/redesign music apps because at their core they are very simple and complicated at the same time. Most of the time they only have a hand full of elements on screen at once, they all use mostly the same meta data and most people get that it's a music player right off the bat.

Our team uses Sketch > Zeplin. We also use many a prototyping tools from Invision, principle, Flinto and after effects. For the love there needs to be more prototyping tools for android that aren't horrible.
