Body
In general, it's not possible to figure out what other apps are doing with events, no. It is also not possible for you to find out when the play button in iTunes is pressed. Even if you were to catch the mouse down event, you'd have to somehow figure out whether iTunes's play button was under it at the time. What you can do in this case, however, is register for the notifications that iTunes posts when a track starts playing. Dave DeLong has laid it out, in <a href="https://stackoverflow.com/questions/4888816/objective-c-mac-os-x-distributed-notifications-itunes/4889556#4889556">another answer</a> here on SO. <pre><code>// Register for notifications, perhaps in awakeFromNib NSDistributedNotificationCenter *dnc = [NSDistributedNotificationCenter defaultCenter]; [dnc addObserver:self selector:@selector(iTunesTrackDidChange:) name:@"com.apple.iTunes.playerInfo" object:nil]; </code></pre> <hr> <pre><code>- (void)iTunesTrackDidChange:(NSNotification *)note { NSLog(@"%@", [note userInfo]); } </code></pre> This doesn't give you everything you might hope for; <a href="http://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/Notifications/Articles/NotificationCenters.html#//apple_ref/doc/uid/20000216-111391-BCICDDAC" rel="nofollow noreferrer">Distributed Notifications</a> are expensive, and so iTunes is frugal with them. You get a notification when a track starts playing, and that's it; no stop, no volume, no distinction between jumping tracks and starting playing from a stop. The notification does have plenty of info about the track itself, though: pretty much all the iTunes metadata, and some of the file info. Hope that's useful!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
