I noticed that Sten posted a photo from the JavaOne pavillion that happens to show the Music Explorer FX in the background.
Using my photo-forensic skills, I’ve extracted a detail that shows the Music Explorer FX:
Here you can see Franz Ferdinand, surrounded by a set of similar artists, as well as a audio player, along with graphics that show familiarity and hotness (all derived from the Echo Nest). The Music Explorer FX is pretty neat. I hope Sten releases it soon.
