Hi all,

I've got a ford focus w/ a factory deck that is beginning to sound bad. The
deck loads tapes into a little bay which drops down about a half-inch to
meet the heads, and it defaults to radio if it doesn't have a tape loaded.

I've picked up a cleaner cassette, but for some reason it just won't
recognize it as a tape! (Most frustratingly, it played the thing exactly
*once*.) Anybody know what it is about the cleaner tape that it doesn't
like?

Thanks,
-D
