The Log File function in Now Playing includes an album log and a track log.

The album log adds one line of information to a file each time an album is loaded into QCD; the line can include album properties and a time stamp, formatted as requested by the user. Similarly, each time a track is played a line of information is added to a (different) file for the track log.

In a future version of Now Playing, it may be possible to view statistics based on the log file.
