Using HiJack's builtin Web Interface, songs with a " in the title (such as a song that is a 12" Remix) do not stream. I get a 404 instead. If you look at the url generated, you can tell the " creates a broken link.. The CharcoalGrey interface has the FID in the url, rather than the track title (I'm not sure how all that works) so it has no problem streaming these songs...

Is this a known issue that took me a year to figure out?
