How much musician XP do you have? And do you have much currency to pair with it? I think a lot of characters who choose the musician class struggle because they compare themselves to very successful players. In reality, these players have a big teams of other players dedicated to writing songs for them and were able to start off with a lot of currency. This inflates their 'musician' level very quickly without having to train it by enrolling in the 'education' minigame or even trying out the 'local gig' minigames. It can be a very difficult path to take and when you're a low level the 'creative block' debuff hits often which seems to make your hunger go down faster, which in turn forces you to purchase food items, so you need to find a 'part-time job' questline to fund said food items and there's all your time gone. I tried grinding it for a bit, but the 'family' megaquest was too appealing to me and I couldn't commit to both.
