Thank you for trying. Music files would be a bit much for dial up. I wouldn't expect too many to try and listen, but music lovers that download music usually are on broadband.
The person in the USA could here it Ok once, but is having trouble listening now, so I was wondering what type of media player does the Mac have? and does it play automatically when clicking on the start of the media player? One other thing I did ask if they had their media player volume turned on, as it does happen.
