I'm curious to know if there are some music rights problems or something -- that's a thought that occurred to me. It'll be interesting for those who have it to let us know if they are original hits.
I got an email "Update on Order-Power Walk Through The Decades" telling me it has sold out and is on backorder. "We are awaiting stock to ship from Australia, which will hopefully be next week and on its way to the USA shortly after. This means there is a delay on your order." They say I have the option of waiting or refund.
