hi everyone
I finally want to subscribe to music streaming service. I already did some research but i'm still not sure which one i should choose. So really appreciate your help. What are experiences with the different streaming services?

I can recommend you deezer. I like that Streaming Service very much. But a lot of my friends are using spotify. so i guess it depends on what you are looking for in a Streaming Service. I am sorry i couldn't be of more help.
PS: I found this article maybe this can help you

I was thinking about signing up to Amazon Unlimited Music. I think it's brand new! They say that you're able to olisten to music offline by downloading tracks. No idea how this should work but it's sounds great.

I'm using Deezer and really it. It offers a lot of different Music and is very userfriendly, and you also have the possibilty to hear the music even when you are offline. but what i don't like is that you dont really have the music. Thats why I have been looking for a Programm that can record the music so i can put the music from deezer on other devices. maybe this is also interessting for some of you. Its called tunbite. http://audials.com/en/how_to_record_internet_radios/spotify.html

From a personal experience I think Boomplay will serve all your craving
