I’m a musician too, for over 30 of my soon to be 40 years. I too don’t care about its “success” I’ve made a grand total of $11 and two tall boys performing, and easily spent a few thousand on gear/recording software (not to mention the running joke that I’m not allowed to buy more guitars). I play/record inconsistently but I love the hell out of it when I’m in it, and I’m just tickled that other people have enjoyed anything I’ve written too. Good for you!
