Are you sure it isn't for a set list of twenty-five songs that THEY choose? I bought an Itunes card just like this on listia and it was awful - all you got were 25 songs I never heard of. Auction said the same thing - $25 - 25 songs.
Is there an expiration date? I just won an auction for a Jack Johnson song and the code had expired. Seller was really nice about it though and refunded my credits because they didn't realize it til after the auction ended. I just don't want to go through the hassle if there was a way to check beforehand. Thanks!
