Hey, if you like discovery try Audiogalaxy Mixes - we just launched it a week or so ago [1]. We think it's better than Pandora (much larger catalog, smarter algos, more input types) - tell me if it's not. It's free on the web (no ads) with a free trial on mobile, after which we charge a small fee to cover licensing costs. If you email viraj@audiogalaxy.com with your account I'll comp you a free month. I'd love to know what you think.

Here's a Mix I've made, for example: http://www.audiogalaxy.com/mix/87-Guitar%20Gods/?
