I have been using spotify for 2-3 years, deezer for some months, rdio and also xbox music. I downloaded Beats today and I got to say, wow!
Spotify is great, but for windows phone, the app is horrible.
Deezer, the app looked great and worked, but had it's ups and downs.
Rdio, the whole service was not good at all.
Xbox music is good, but the app doesn't look good. They should've used the same UI like the one they used on iphone and android.
But yeah, Beats Music was just awesome. It got that radio thing with the sentences, love that part. "I'm in the car & feel like playing with fire with no pants on to oldies" haha, so much fun.
And it got everything I love from all of the other music services. Just the thing that you can add your own cover art, makes the whole experience better. The price wasn't too bad neither.
I also had difficulties finding the search bar haha
The only con is that it's very slow and sometimes very laggy too. But I guess with an update that will be fixed.
