Spotify integration data traffic via mobile music flat plan?

Is the new Spotify integration using the Spotify flatrate data traffic which I’ve got on my mobile data plan (T-Mobile Germany Music bla) so I can use it via mobile network 3/4G?

Yes, it’s the same as playing music with the Spotify iPhone/iPad app.

(We would otherwise probably have paid a lot of data charges in the last months while testing the update here in Germany. ;-))


How is it when I connect my mac via hotspot with my Phone and use the Spotify intergration? Is ist also the same ?
