Yahoo! MP3 assistance?

I have tried to download an album (more specifically, Deerhunter's Halycon Digest) and my credit card was invalid, which could make sense. Only, after it said payment was failed, I tried again with another option I had, leading to a page that asked "are you sure you would like to buy this?" somehow, i paid for the album, but im not entirely sure where the digital download went, considering it didn't download anywhere. i also received payment information.
