I tried searching for a topic like this here, but didnt seem to find anything major about it. What is your preference, Pandora or Last.fm, and most importantly, why? This can be for PC/Mac or Android use. I have been using Pandora for a few days and have been blown away by what artists it is bringing to me. After putting in 2 bands and liking/not liking about a dozen, it is really nailing the particular music I enjoy. After realizing that the free version has a monthly time limit, I decided to check out Last.fm and see what that hype is about. Been listening for a while today and so far it isnt really hitting any spots with me. I put in more artists to begin with, thinking it would help pinpoint what I enjoy, but it seems to have picked up one artist over the others and playing songs similar to that artist but not from that artist. Also the sound quality of Pandora seems to be more consistent, last.fm one song is louder then the next is super quiet, stuff like that. So far I am leaning towards Pandora, what are your thoughts? Also if anyone has specific comparison statistics like trial period vs free, features, quality, mobile use, etc.
