Hello

I am planning to buy Spotify Premium in order to be able to listen to Spotify on my Android device. Before I do so, I have some questions I didn't find the answers for (yet).

1) When I've downloaded a playlist for offline mode, does it use my Internet connection for playing the playlist while being in online mode? In other words: Can I use offline playlists in online mode?

2) If I search for a specific album in Spotify (which I actually have in one of my offline playlists), does it stream from the Internet or use the offline playlist to play the songs?

3) If I have the same song in two different playlists I want to download, does it store the song on my device twice or just once? Does Spotify download each song individually or just the playlist in one file?

4) How much space does a 3-minute song downloaded for offline mode approximately use on my device?

EDIT: found the answer:

Quality 96 kbps => 0.72 MB per minute.
Quality 160 kbps => 1.2 MB per minute.
Quality 320 kbps => 2.4 MB per minute.

I hope you can help me and thanks in advance

Simon
