Unfortunately not everyone is a DIY person, or someone lucky enough with an audi like yours who knows how to fix MyMusic to your satisfaction. They may not have the ability to express what they find lacking properly to their audi so their audi would know what to adjust either.
It would still be better to leave the original legacy Music program alone and available, then add MyMusic with the ability to modify it further to one’s heart’s content on top of it. That way, everyone is happy, including those who don’t want to mess around with anything at all, or have to ask their audi mess around with anything at all.
But I agree that it’s not a deal breaker like what people might have thought before, where they can’t go back and didn’t know if they could go forward with adjustments.
