When viewing the Music (iTunes) library, be able to identify the tracks that have already been imported into My Collection. (like Traktor)
I really like djay’s advanced mix-related features and enjoy DJing with them so much that I would definitely switch to djay.
However, djay’s song selection support features, such as library management and searching, are poor compared to Traktor’s.
I am a DJ who emphasizes song selection first and foremost, rather than the technical aspects of mixing, so I strongly urge more library-related features.
