Unhandled exception error when trying to edit mp3

For the last few days I have been unable to update my Artist Comment on any previously uploaded MP3.
I enter the edit page, change the text, click submit and get the following:

SqlDateTime overflow. Must be between 1/1/1753 1200 AM and 12/31/9999 11:59:59 PM.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlTypes.SqlTypeException: SqlDateTime overflow. Must be between 1/1/1753 1200 AM and 12/31/9999 11:59:59 PM.

I am getting concerned as my song "lets learn spanish" has been getting a vast number of downloads (30 in 5 days) but not rated.
My stuff is not that popular!
Could this be a serious bug?
