Use a cookie for storing authentication token instead of sessions (sessions can't reliably have their expiration time extended without globally modifying the php ini file)
Rename $u_user to $this_user for better clarity
Change all uses of $_SESSION['user'] to the existing '$this_user' variable (and reduces the risk of stale user data being used for stuff)
Remove sessions altogether, since they're no longer being used for anything (they can be added back if anyone really wants them for something, but be aware that you'll have to recreate your session in auth.php, not just create it at login, since the PHP session is likely to expire a long time before the user's authentication token)

Some tracks were reported as '7 days ago', others as 'about a week ago' and others still as '1 weeks ago'.
Now these are all 'about a week ago'.

Add "Listen" page, allowing users to stream tag radio stations directly from the website via the JavaScript player
Give the JavaScript player support for stations
Add radio authentication to the User class for use by the JavaScript player

Figured out why an empty "$user's Top Tracks" heading was appearing at the end of user-recent-tracks. That was confusing the hell out of me!
