// TrackSum v1.0
// If you are editing a page, this script gives you a button to click and automatically sum up all the track lengths in [[Template:Tracklist]] to provide a total length.
// Keep in mind that officially-released runtimes should be used if available. Some albums are longer or shorter than the sum of all track lengths.
// NOTE: This won't work if you have hh:mm:ss track lengths. I don't know if this ever happens, but if it does, they need to be in minutes.
// Of course, since 60 is 60, this will work on mm:ss as well as hh:mm track lengths, if they're all used consistently.
