If you have problems with 20+ hours than I must be like really bad off. Most of the the stuff that I do takes 50+ hours . I know that professionals spend bunches of time on certain tracks. The engineer/mixer I’m doing an internship with spent days with a producer to find the right snare sound . So at least you get a whole track done instead of just one snare sample lol. Also for me I’m still learning a lot and very particular on how everything sounds. The more time you spend the more likely it will sound better and well rounded.
