"the circumvention of data caps sold by Deutsche Telekom (totally different from T-Mobile US) for users of Spotify."

This is not net neutrality, it is just Deutsche Telekom bundling a product with their subscriptions. It only becomes a net-neutrality problem if DT begin to prioritise Spotify traffic over other traffic (ie; let's allow Spotify traffic, but throttle iTunes).

Considering that you can't really use music streaming with the usual caps here (200MB, 500MB, 1GB, 3GB), it makes it impossible to compete with Spotify, unless you also pay DT.

Therefore, in the context of mobile, all other music streaming services are essentially throttled when compared to "exclusive partners of DT."
