this would all depend on whether you where using 'tunes!' or 'tracks'. tunes being stuff with breakdowns and crap, stuff that goes places. tracks being a dj tool that doesnt do much in itself, but leaves you loads of room to hack the crap out of it. i can see why you'd have to drop 'tunes' in the right place, but to mark them, hmmmm. surely you should ahve the skills to know when to drop them if you're even going to bother getting 4 dex out.
