I’m told this is currently the top selling greeting card in the United States. It is kind of cute – hamsters apparently dancing on the cover. It’s when you open the card that you realise why it is a top seller. This music played from within the card is infectious. You can hear it at hamsterdance.com.
Sound cards are all the range in the US. There are hundreds and hundreds of them from licenced product based on popular movies through to cards based on iconic songs. Given the huge success in the US I am surprised that we don;t see more of them here. The samples I have been given would sell easily here.
