General Reccomendations for streaming music app?

[sisterskeeper 4 11.3.1]

So, my current favorite music app is an app called Slacker.  It is a free streaming music app with option to upgrade, and probably the most frequently opened app in my library.  I've been using it for a year, and love it to pieces.  

 

What I love about it is the fact that it works by radio stations that you can customize by asking it to play your favorite songs more often, how often you want it to add in new artists, how popular the songs it plays are and how old they are.  The songs on the stations go together beautifully, and they have niche stations, like my beloved Movie Soundtracks station and my 90's country.  They have features that explore artists, like a station with their songs and songs by the artists who inspired them, or where that artist acts as the DJ for the station.  I love the offline play, to cache a station and play it while I am not on a wifi or data connection, though seldom get a free upgrade.  I like being able to set up a station composed solely of songs by a single artist when I manage to nab a free upgrade.  Being able to cast to my TV is a wonderful feature I still use from time to time.  

I don't like the ads.  When I started using Slacker, there were far fewer of the ads, and they were more tolerable.  Lately they are for more present, and I find that they tend to be for stores that don't exist in Canada...And more and more of the app is getting tucked behind a pay wall, with the ability to take advantage of free upgrade offers vanishing more and more.  Add that to the fact that there seems to be no hacks for it, and that few people seem to have even heard of it...I am looking for a reccomendation to replace it as much as I can.  

Are there any music streaming apps that have the more 'Radio Station' setup?  I have Deezer, but it seems to work mostly via playlist and album.  I tend to use it when I want to play a specific song or album, but not much otherwise.
