It looks pretty good to me.

For use cases where you just want to assemble a playlist and don't need to
carefully manage data buffers at the application level, I think a higher
level API that lets you precisely schedule playback is a lot simpler for
authors. See the examples at example.

“You have heard that it was said, ‘Love your neighbor and hate your enemy.’
But I tell you, love your enemies and pray for those who persecute you,
that you may be children of your Father in heaven. ... If you love those
who love you, what reward will you get? Are not even the tax collectors
doing that? And if you greet only your own people, what are you doing more
than others?" [Matthew 5:43-47]
