The ads alone would make me throw off my headset in disgust.
For a mobile, there is a modded apk,I've never heard ads there. For a PC, web player in Firefox with uBlock Origin, there are no ads at all there. The same goes for Tidal, I've never paid for these apps.
The worst ever suggestion and unfortunately the most upvoted. Do not ever download music from youtube, free-mp3-download was a front-end for deezer with flacs and 320 kbps mp3 and music on youtube is only about 160 kbps, that's kinda okay for streaming but absolutely ridiculous if you want to download and keep it.
