I'm planning to subscribe to Napster music service because it's cheaper than Spotify, actually Napster premium costs 4,95 euros and Spotify costs 7 euros. I want your opinion about Napster, is it good or not, is it similar to Spotify, is it fast as an app ? I chose Napster because my carrier (Vodafone) has a special offer for its subscribers, but i'm not really sure about it.... Can you help me ?
