First, thank you for the awesome project!

I have multiple, large music files I want to stream from disk, like this:

• play song A
• stop song A, start playing B
• stop B, continue playing A
• etc

When a song plays all the way through, I rewind it (via. streamer.Seek(0)).

Given this kind of usage, what I've come up with is to have ctrl := beep.Ctrl{...} where I keep changing ctrl.Streamer to the song I want to play.

However I'm confused about when I need to call speaker.Play(). Do I just call it once, after constructing ctrl? Or every time I change ctrl.Streamer? Or only after I rewind a streamer?

Thanks for any info!
