When one clicks on the time slider the current behavior is to move in an increment forward or backward if the click was left or right of the handle respectively.  I think it might be better to simply set the new position to the point of the click.  It makes better use of our spatial resolution and makes it much faster to use.

Use case:
Position half way through a song

Now:
Click and drag handle half way across the slider
 or
Click a few times on the right of the handle

Future:
Click once half way across slider
