This is horrible.Its just coverflow except portrait. Nothing 'Beautiful' about it.
I'm assuming you don't find the interface particularly appealing, but do you think that others might? From the comments in this post, it sure seems like it.
The OP was able to articulate an interesting insight into why other music apps were lacking for him (genres aren't a useful grouping mechanism), and build a (beta!) solution. That's beautiful.
From the demo one thing was clear to me: that thought and care went into making this, and that should be respected.
Good work, OP. Keep going.
