Resoursepacks and Snapshot

When i went onto the newest snapshot and went into my resourcepack i thought the sound changed but when i put a music disk in the jukebox it played the regular soun i thought it wound play Godzilla's Theme song but i still played Ward and I can understand anything when i used my pack it made the writing and messed up but when i switch back to default and log out then log back in it is fixed. And when i try to switch Resourcepacks it crashed my game. Also all my textures are messed up in my Resourcepack it looks like this
