It's interesting how easy miscommunication happens. I said it's mainly for one thing, not the other. I didn't say it wasn't for or never used for other purposes. People are misreading that "not the other" as though I used a period instead of a comma. Read it as "not mainly for listening" and you'll read it the way it's intended.

Carry on listening to a format most people use for purposes other than listening if that works for you. I can't stop you with a simple dependent clause. You're safe.
