Hello. I have a question. I am using djay pro 2 on mac. Also, I own Spotify premium account and have downloaded some of the playlists for offline use. I know that I cannot use Spotify resource from djay pro 2 without the internet. The question is next: If I am connected to the internet but playing Spotify offline songs (via djay pro 2) does it still use mobile internet data to access those songs or it gains access from the computer's hard disk?
