is this service even really worth it?

I've had nothing but issues since joining mainly these two. Deezer will just for some reason add songs in the middle of my playlist. I never asked them to add songs I purposely curate playlists for purposes and to have them at songs is not only annoying but extremely frustrating. This app will also just stop playing music for no reason as well. I'm in the middle of a workout or I'm in the middle of being with a client and all of a sudden the music just stops it's not like I got a phone call or anything it just stops playing. I'm trying to figure out why people use this as a paid service, can someone please enlighten me? Are these supposed to be sought after features?
