Hello. What software is recommended to create a simple DJ mix. All I need the software to do is (1) import chosen songs from a "Dancing" playlist in my iTunes library, (2) edit some of the songs so that they begin at a certain spot where the dancing segments begin, ie edit out long non-danceable intros, and then (3) automatically mix with the next song on my playlist when the previous song is finished, or mix randomly to another song in the playlist.
