I was having fun in creative making a big mine cart track. I tested it out. When I left the mine cart it kept on playing it's sound. I then went on to try it out on some other worlds. exactly the same. I broke the mine cart. still the same. The only way to stop it was to press Esc.

What I expected to happen was...
When I left the mine cart, I thought the sound would stop.

What actually happened was...
The sound kept on playing.

Steps to reproduce...
1. Make a mine cart track.
2. Get in the mine cart.
3. When you get to the end, get out the mine cart.
4. Notice the sound is still playing.
