If i use the phrase "this song was given to me ..." it means the song was given in writing by the author or performer (ie. he gave me a lyric sheet, minimum). If I use the phrase "I got this song from Joe Bloggs", it means I've asked Joe Bloggs if he minds if I sing it, and he said that it's OK for me to sing it. If I say "I got this song from a record of Joe Bloggs" it means I haven't asked him. If I say "I've stolen this song from Joe Bloggs" it means I've asked him, and he's told me he doesn't want me to sing it. I usually respect that, so I only use the phrase if I'm doing a song by request, for someone I respect highly, and the songwriter has said "I would prefer it if you didn't sing it" rather than "NO!"
