My iPod Classic died and most of the songs I had on it were from friends' iPods. I am thinking about getting an iPod Touch because I was able to find most of the songs on Spotify. It is my understanding that if I get Spotify Premium, I can listen to my music library when I am offline (when driving, running, etc.) Is this correct? Also, if I am not near an internet source, can I search for new music with Premium, or can I only listen when offline?
