Fascinating + fun music link to explore different music styles:
The "how to" is at the bottom of the map: "This is an ongoing attempt at an algorithmically-generated, readability-adjusted scatter-plot of the musical genre-space, based on data tracked and analyzed for 1264 genres by The Echo Nest. The calibration is fuzzy, but in general down is more organic, up is more mechanical and electric; left is denser and more atmospheric, right is spikier and bouncier. Click anything to hear an example of what it sounds like. Click again to jump to the middle of the song, a third time to stop it."
There also ist a Page with play lists
The songs run via Spotify, i don't have an account there, but it still plays (maybe it's based on a 1-month-trial-system)
