Looks great!

I guess it depends on how other clients render them? Is this a standard kind 1 with hashtags and audio attached? 

The only thing that feels out of place is the close button (assuming this is what it is) at the bottom as it’s rather large and has the same level of emphasis as the share button. 

I love that you separate the tags field! This should encourage more hashtag usage which could be great at helping others discover music content. 🙌

I’d play around with enabling that setting by default to help people broaden their reach. People may appreciate it, or hate it, just have to wait for user feedback on that one.
