I admire your music.
Is this correct English? (I know we should say 'appreciate your music'.)
Thank you in advance.
Sounds fine. In fact, I think that "admire" better expresses what you're trying to say.
Thank you very much, Slick. And can both words be used in this sentence:
Everyone was clapping and appreciating/admiring your music.
Thank you again.
*Not a Teacher*
Both work equally well in that sentence. "Appreciating" may be the best choice for the context, but that's just my opinion.
