Resource Packs that worked in previous snapshots no longer work in the latest ones.

What I expected to happen was...:
I created a resource pack with custom music for an adventure map. I wrote a JSON for them. And converted the songs to OGG. This I compressed it to a ZIP folder and placed it in the save file of my world. It worked almost perfectly in all snapshots previous to 16w02a. I expected it to keep working.

What actually happened was...:
It stopped working as soon as I updated to 16w02a. Now I cant figure out how to fix it.

Steps to Reproduce:
1. take a song around 3 minutes and convert it to OGG.
2. Create a Resource pack folder tree and add put the converted song into the "sounds" folder.
3. Write a JSON that is similar to the attached. Providing the name of the sound file and set to "stream".
4. Zip the resource pack folder and name it "resources.zip" place it in the save file of a world and open the world.
5. Use the /playsound command to try and play the sound according to the name you gave it in the JSON.
6. It should say it played the sound but not make any noise.
