I'd be great to have non-audio media displayed more prominent on the shared page. Right now photos and videos are quite hidden behind the artwork. Especially when I already have a performance or music video, I don't want the client to miss that - but it's likely to miss it at the moment.

If you provide options to make the page look more like a landing page, Songbox could also be used as an EPK for applying to gigs, pitching to record labels, etc. Why only put the songs into focus?

My suggestion:

First add an optional section for videos right underneath the songs. And another separate section for photos.
