Troff is a Google Chrome browser extension that lets you play and manage music. With this utility, you can create and add start points anywhere in a track, slow down songs, or loop a part of a musical piece.

It's actually a great tool for dance rehearsals or if you want to learn to play a song on an instrument.

Once you download the program from its official page, you'll see its interface. By default, it points to the Music, Images, and Videos folders, but you can add or deselect folders from the Select folders option at the top. (It accepts images and videos.)
