DJ with millions of tracks, on your phone

Love these apps they make me feel like
@virtualgoodz You're killing it with your set right now!
@virtualgoodz Yeah! Naturally, I want to just press 2 buttons and suddenly have a Tiesto-like set.
This is so cool. Great interface BTW: Edjing ≠ Edging
@kristofertm my thought when I first saw this too. "Careful with that name."
@kristofertm @bradenhamm My first thought too! For those curious: http://www.urbandictionary.com/d... (slightly nsfw)
It looks eerily similar to DJAY 2 (http://www.producthunt.com/posts...) except this app is free. Interesting.
@irvingtorresyc There is always someone who is hungrier out there. Gotta make sure your software/app is defensible.
Hasn't this one been out for quite awhile?
I love products that make you feel badass (reference). Crossfader by @seth and team is similar DJ'ing app.
