This is a wonderful new program - the Spotify integration is immensely useful. But I do cannot stress enough the value of STORING LOOPS in a DJ software. If you have only a cue point stored versus an entire loop, you have no idea how long you can play the song from that point, and therefore have to listen to the entire loop you've just created before you know it'll mix well. That can add up to 8 seconds on transitions. Moreover, programs like Serato and Traktor allow you to quickly adjust the loop you have stored; move, halve or double it. For me, and I think many other DJs, this is the key difference between using djay PRO as a fun mobile app and a professional music software.
