Denon prime 4 music download

hi there where can i get 7 to 8 minute remixes to play on prime 4 or just longer tracks

I’ve been using beatsource link and they have a lot of great DJ edits of tracks, mostly RnB hiphop genres but do have a lot of commercial dance music too. If you’re more House, EDM, Trance etc then Beatport link is good.
