The music library does not recognize existing playlists already visible on the phone's Music app. Also library info is not refreshed even after phone reboot/app cache cleanup/app reinstall. This is major issue and needs to be addressed immediately. I bought Hercules DJcontrol Mix and this "natively supported" software just ruins my purchase. Also us Android users should be able to remap the controller functions, edit FX and samples just as iOS users can. It would be also nice to be able to see BPM of the songs in the library, but I understand the limitations (can't analyze songs before they are loaded in the deck.. but still, try please). Oh, and yes, I bought the pro version of Djay, which was a waste of money as well.
