When entering a tracklist, if you enter a time with three digits and don't type the colon, it gets entered correctly. Example: "123" => "1:23". However, if you enter a time with four digits, it does not work as expected. Example: "1234" is expected to result in "12:34", but in fact displays "1:234", a rather nonsensical time. More than four digits is similarly nonsensical.

Times entered with 1 or 2 digits also do not display in a meaningful way. "5" results in "5", expected would be "0:05" with a possible argument to be made for "5:00"; just "5" is wrong either way.

The workaround for this is to use the colon, which always displays OK, but is inconvenient when 10-key'ing.
