Adjust main-menu wording
Hopefully this isn't too trivial...
On the main menu, the description of the first item is an indicative statement about what the device will do, the descriptions of the two middle items are imperative statements about what the user can do, and the description of the last item has no action/verb at all
This makes them all consistently imperative (which seems most typical in other software)
Also changed 'tracks' to 'track', since you can only play one at a time
