I'm relatively new to Spotify and have a premium account. I've just started building my library by "adding" songs and albums. However, I use 3 different devices (Mac, iPhone and iPad) to listen to Spotify and the Library is different on all devices.
Is this the intended behaviour? It seems to me be the Library should be tied to a Spotify-account and thus be the same on all devices connected to that account.
Thanks in advance,
