I feel they must know the difference(and anyone would assume that) but will answer you in good faith.

I can listen to songs in their entirety in my head and it's nearly as satisfying as actually hearing. I can turn it down halfway thru and still be in sync 30 sec later.

That's not to flex only to illustrate how similarly I experience the real and imagined phenomena. I can't stop the song once it's started sometimes. It feels that real.

My voice sounds exactly how I want it to when I speak 99% of the time unless I unexpectedly need to clear my throat. Professional singers can obviously choose the note they want to produce, and do it accurately. I find it odd your own voice is unpredictable to you. Perhaps - and I mean no insult - you don't 'hear' your thought in the same way.

Edit I feel it's only fair to add I'm hypermnesiac and can watch my first day of kindergarten like a video. That's why I can listen to whole songs in my head.
