I think there is a lot of truth in what you say. Most of our users in our target focus segment ( i.e., people who already play 2hs a day ) feel very confident in learning, practicing, playing/recording songs. Making music is hard after all, requires a lot of dedication. A lot of people aspire to get there, but they are not confident, or know how to get there. That's why lessons are so important in this hobby.
Since our initial focused segment is big enough for us to get traction, we are not currently focused on expanding, but we will do so in the future and asking ourselves/our users the questions you suggest seems to be a good idea.
