I keep getting the same error - for me its been both Bass and the Special Stage that have had problems.
I've deleted the files from the memory and then redownloaded them but that only works for the next time you load the game - after that it will popup with the "Failed to read downloadable..." message about 75% of the time.
I'm sure its coincidence but it was the first time i'd used the Xbox.com marketplace and queued DLC downloads to the 360 (queued them up whilst at work ready to download when i got home)... its now kinda put me off doing that again! ^^;
