MP3 Hint is an InfoTip Shell Extension. After installation, hovering the mouse cursor above any MP3 file icon will display a hint which will contain informations extracted from the TAG of this MP3 file. You'll see title, artist, album, year, comment, genere, and track number. It can be very useful when you have a lots of files with meaningless names (e.g. as Track23.mp3). With this extension, you will quickly recognize any MP3 file, without the necessity of loading it into a MP3 player.
