if you’re into music-recommendation & -exploration services, you might wanna check out Musicovery. set your preferred mood (energetic, dark, positive, calm), period (80ies, 90ies etc.) and musical genres, and Musicovery will generate a matching - though static - playlist. while this is definitely inferior to Pandora’s dynamically adjusting streams, Musicovery offers a beautiful flash-based visual chart to freely navigate the tracklist (something Pandora’s free-service offers only under restrictions due to licensing). imagine a similar interface to Pandora’s musical genome database, visualizing all sorts of musical connections & dependencies…I’ld gladly pay a monthly fee for that! 
(btw, Musicovery charges EUR 2,-/month for its high-bitrate streams, LoFi is free)
