Is Pandora better than LastFM?
Dude.
....Duuuuuuude. Pandora is amazing. Last.fm is crap. When Pandora was available in Japan, it felt like one of the reasons the internet was useful. Every day I'd tune in, find new things, hear songs I'd never heard before, but were instantly enjoyable because of their shared characteristics with other songs which I'd told Pandora I liked.
Last.fm on the other hand saw that I listened to Rob Zombie, White Zombie, Limbomaniacs, They Might Be Giants, Laurie Anderson... and kept suggesting, "You might like Coldplay." Wat?
Last.fm pushes the label's choices, while Pandora attempts to make qualitative associations.
