Can't play custom records 13w42a-13w42b

I've created a Music Disks Resource pack and custom hurt sounds, and have everything set up as normal, but it only plays custom hurt sounds, and not the custom records.

The Pack:http://www.mediafire.com/download/ble5wd1m73qeiwd/Pack.zip

It was too big of a file size to upload directly to here.

EDIT: I've been browsing around and it seems Records have been buggy in general. This must be related.

EDIT 2: I'd still like a mod to confirm this so I don't have to pull my hair out trying to fix what is perfectly fine.

EDIT 3: It seems that my game isn't using ANY resource packs correctly. Possibly related to several other reports.
