I have a number of music cassettes and CDs. My favorite is a CD of the "Henry V" tunes from the movie. I've never seen the movie, but would like to someday. My sister had both the cassette and the CD. She gave me the cassette. Several years later I told her I couldn't play it any more because I had worn it out. By that time her tastes had changed, so she wasn't really into it any more, and gave me her "Henry V" CD.
I have loaded it onto my desktop PC, and sometimes play it while on the computer.
As for regular singing music, I don't have one favorite, but like a number of different tunes.
