I think you can join Spotify via their website. Then, it's easy. Just search and play. Another one that let's you choose free music is Grooveshark. I use that when my limit on Spotify has run out. Can't remember how many minutes you get.
Techno idiot here. Just wondering how to get the most out of last.fm and spotify.
I was hankering after a sort of interactive thing where I could put in a few tracks and then it would play me some suggestions and then I would play a few more myself and I would build up some sort of library. I've tried the radio feature on last.fm but if I put in my featured artist and play, say, Stevie Wonder Radio, it doesn't then give me an opportunity to add other artists that I like to the same station iyswim?
Can I do this? And how do you use these things? (And what do you call them? platforms, channels, stations, apps???)
