This weekend The Echo Nest is releasing some new remix functionality – Earworm and Capsule.  Earworm lets you create a new version of a song that is any length you want.  Would you like 2 minute version of Stairway to Heaven? Or a 3 hour version of Freebird? Or an Infinitely long version of Sex Machine?  Earworm can do that.   Here’s a 60 minute version of a little Rolling Stones ditty:

Capsule takes a list of tracks and optimizes the song transitions by reordering them and applying automatic beat matching and cross fading to give you a seamless playlist.  It is really neat stuff.    Here’s an example of a capsule between two Bob Marley songs:

It makes a nice little Bob Marley medley.

Jason writes about Capsule and Earworm and some other new features in remix  in his new (and rather awesome) blog:  Running With Data – Earworm and Capsule.  Check it out.
