I just finished recording a mix that had a few transitions that were really tough to work out (unsurprisingly one involved a John Tejada track, as he has quite a few tracks that have given me trouble) and I was just curious if there are any tracks that you folks have had a particularly difficult time trying to transition in and out of?

I'm strictly a home DJ but I do record my mixes so I can listen to my favorite tracks in a proper mix. It's been a lot fun figuring it all out and although it can be frustrating, one of the most fun things about it is getting a uncooperative track to fit. Would be interested in hearing what other folks have struggled with.
