Mad_Cyril I do it whenever I buy new tunes. Usually about 20 every Friday. Takes me about 3,5 hours. And depending how you play tunes all you have to do is listen to the tunes. No adding cue points etc. Like when I played stuff off burned CDRs. There was no other preparation.
For me doing a mix properly takes usually a few weeks, I try a lot of different combinations etc. But not done that since the lockdown started. Just been playing for fun every weekend for hours, and I always record. Every 4th session or so seems to be good enough for release.
Doubt I will do a thought out mix in awhile, this has been more fun.
