"So-and-so taught me this song of his/hers" would clearly express a claim that you met the artist in person. The other phrases under discussion here are more ambiguous; in fact, we've seen that some folks have had exact opposite interpretations of "from the singing of" vs "learned from."

As far as I'm concerned, that ambiguity is completely OK. If anyone is truly concerned about whether you actually met so-and-so in person, let them approach you off stage and ask.

I have had a (very) few encounters with noteworthy artists, and indeed even been greatly encouraged by their reactions to my own efforts, but I generally try very hard NOT to drop their names or otherwise claim their reputations as somehow enhancing how I might be regarded. I save my stories of these "brushes with greatness" for close friends, only after I've gotten to know them quite well.

Well, with the exception of a few indiscreet postings on Mudcat. But not this time!
