I get a lot more compliments on music that I just make on the fly because I’m feeling inspired (regardless of genre) than when I have a goal in mind from the start, but wasn’t necessarily just going where the inspiration took me.
Typically the best “method” for me, is to sit down, design a sound that I like, and just start building something from there. Usually a big loop, then copy, paste, subtractively edit, then go back and add changes, sprinkles, candy coating, etc. afterward. Inevitably the genre changes part way through, because I decide that that initial sound works better in say, a break, instead of techno, or in space music instead of house. (or whatever…)
Very rarely going in with a mission works out nicely, but most of the time, I either stop part way in, or it changes wildly from where that mission was initially headed. If the creative progression was natural though, and not forced in any way, that’s when things turn out well. Then I just have to accept that I made something better, that wasn’t what I initially wanted, and try again another time.
