First off, try to find songs that mix harmonicly (in key). You’ll probably be playing quite some songs parallel to eachother, so it’s important the keys match.
Second, skip most of the intro’s and breaks. If you want to fit 10 songs in 10 minutes it’s going to be drop after drop after drop. If you want to play an intro or break, play it parallel with the previous (or next) song. Combining acapella versions of tracks with other instrumental tracks can also help with playing more ‘tracks’ without it all becoming too crowded.
If you want to get really tricky, try mixing the break of song 1 into the intro of song 2 (should be a reasonably long intro) which then leads to a double drop with song 3 (song 1 should be mixed out by then).
