My Best Buy has had an Apple store within a store for a while now. At least a couple years.
I remember reading that Samsung would be doing this too at select stores.
I put all my music in the cloud with Google Music manager.
I was using iTunes in the cloud with my iPhone so I was used to listening to my music this way.
I use Airframe
I originally bought it for my iPhone 5 but it's spring-loaded so it fits any smartphone. Very minimalistic and simple too use. It also rotates if you prefer to use your phone in landscape.
