May I suggest cloudplayer

I thought about getting Nitro once, till I noticed it was a monthly subscription

I own both, a iphone X for work and a cheap Motorola G series phone (200 euro).

I prefer my Android phone, the customization, ease of use. With Android you feel more like an Admin, iphone you are just a user for overpriced stuff
