Thank you.
I'm not sure whether that's a TPM question or not, but those are different uses of music that use different technologies that invoke different rights of ours. In a reproduction environment, it's using a reproduction right. In a streaming environment, it's using both reproduction and performance, but more performance than reproduction.
On the TPM side of it, I'm not against locks; I just think they've largely failed for music, and especially on the reproduction technology side.
