Most of the QVC music used to be taken from a library of music clips. Some of the early stuff QVC used, used to crop up on other shows like "60 minute make over", "May the best house win" etc. I suspect they don't have to pay to broadcast them so maybe search for royalty free clips? It's possible QVC commission they're own tunes now and they're not on the web. Didn't Kim from Kim & Co record her own promo song once upon a time?
