Interesting concept, but slightly flowed in my – very humble – opinion, depending on the goal you have for making mixtapes.
If you make them to let your friends and people listen to a live mix then clearly the way you do it is the only “right” way.
However, one of the most important reasons people make mixtapes is to present themselves to others, not in the least organizers, venue managers/owners and program managers. And those people are interested in your “sound” and really won’t listen to an hours worth of mix and check if your transitions were good. That is why, in the mixtapes course, you are not only taught how to fix bad transitions without having to re-record and entire hour worth of tracks, but also how to professionally shorten the track (intro-verse-chorus-mix out for example) so tracks follow each other much quicker, hopefully grabbing enough attention from the listener for them to continue listening a bit longer. Should you have bad mixes in those short sessions, it would most likely be noticed and not helpful for getting booked.
If you are confident you can do your mixes well in public (everyone trainwrecks once in a while), then there is no shame in fixing your mixtapes to have only perfect transitions.
Just my 3 cents as usual.
