I don't hear any of it here. I did hear some garble in one of your other threads earlier today - can't recall which. It was messed up at the start, but when I rewound it several times it cleared up. Very odd. I also heard some garble in one of my "clean" uploads several hours ago - also gone now.
.. and another thing..
Not sure if this may be related, but when I play Soundcloud files from links in these threads, many times they'll stop playing. Never at the same spot. After the 2nd or 3rd restart they usually play through fine. Don't have this problem with the mp3 attachments.
This seems to be a recent phenomenon over the past week or so.
