There's a more cds mod for Minecraft, with different songs on more cds, like CaptainSparklez's "Revenge". Only problem it's a MOD, not a plugin. The cds in the mod are altered so they look different, adding a whole new entity, which server plugins cannot do. I reckon it'd be easy for devs to re-code that though, and make the CDs look like the original ones... But there's still the problem with the music...Not sure if you can code music.
