Being Spotify users can download tracks for offline play, how hard would it be to integrate this into DJing with something like the Prime series? Has this not yet been integrated because of the legality behind it? I know others have mentioned that point in here as well.
To your point, being able to explore new music via requests is huge for me. That’s actually one of the two main sources for obtaining new music. Even if you don’t necessarily play what has been requested, being able to jot down what someone requests, to further explore, is huge for expanding your music library.
