Loading a song while one is playing breaks the UI playback, and the new song starts immediately.

Description

If you load a song while another one is playing, it plays immediately and the play controls aren't really responsive. in fact there's no real "stop" button i guess. even creating a new song doesn't stop the background playing one you load another one.

Steps to reproduce

1. Load a song.
2. Start it playing.
3. While still playing, load a different song.
4. Pattern editor playback stops.
5. New song starts playing immediately.

Note: workaround is to pause playback, hit rewind, then play again, the UI resets itself then.
