From Music Hack Day
Remix a track by reshuffling its bars based on how well different pieces fit together.
 About the hack
Remix:crowdsourced lets you crowdsource remixing of a track! It cuts the track into pieces and let's you decide which pieces should follow the other ones to put it back together again! By asking "Is A:B a better mix than A:C?", it gathers data to be able to find the best transitions from a piece to the other! To find the optimal pop song (!) you need to find the longest path in the graph of transitions (P != NP :'( )
 What APIs, tools, kits or other amenities did you use?
- EchoNest (for Analyse API and Remix library)
- Python, Ruby, Sinatra, FFMpeg, Sox, DataMapper
- HTML, CSS and friends!
