Spotify release preview of new Android app

I'm back from Spotify to buying mp3s from amazon.de and then upload them to Google Music.

Spotify was great for a while. But not only are there huge gaps in the library. The worst thing is when suddenly a few songs in your favorite playlist are greyed out, and when you click on them it says "not available in you country anymore".

Spotify is 10 EUR/month. If I buy a new album each month, then that's still a lot of music. And I can keep it forever.
