1by1 1by1 is a small, fast and handy audio player which is not only small: it provides a smart and versatile environment to handle your file collection and listen to your tracks - with no need for playlists or databases. Tired of creating and updating playlists only to listen to your MP3s? 1by1 plays whole directories of MP3 with absolutely no need to edit a playlist. The program is tiny and very easy to use. it provides a simple interface and a variety of additional features like shuffle, sorting by name, date, shuffle, enhanced mode and some others. This is a basic, but very convenient way to quickly play large numbers of MP3 files without having to fuzz with a fully featured MP3 player. I just wish it could run in the system tray, rather than the taskbar.
