Thanks everyone for your help and detective skills. I have removed all the ads from my site except for Google Ads. I have confirmed that Google does not put sounds in their Adsense ads, so I don’t think it’s them.
I have also removed any unnecessary plugins. I had a few hanging around.
But I just got the song again. (“this is what you want…this is what you get…”) The problem is, the song doesn’t always happen. I’ve probably loaded my site 30+ times today and it happened the first time this morning — when I did more work on plugins — and then this last time.
To the question from the Hack Repair Guy, my old site was called kristainlondon hence why SiteMeter still has that in my link. I think that’s okay.
Any other thoughts or ideas would be great. I’m good at the basics with WordPress but I’m not super sophisticated.
