Boom sounds like it would be an explosion but, in reality, this program is designed to be a very simple music player. The idea behind Boom is to provide an easy-to-use audio player for the casual user. It is portable, so no installation is needed. It plays all the popular audio formats including MP3, FLAC, WAV, MP4/M4A, WMA and more. The controls are as simple as promised with back, forward, pause, volume, repeat, full screen and a few others. It does not seem to be able to find drives properly, a problem if you don't have the standard C: and D: drives for example. In my case, I have my main drive as C and my backup drive (with my music) on F. The program sees A, C and D and 2 out of those 3 don't exist. Under preferences, it allows you to select a specific folder but once again, it does not see my F drive, only C. If you keep your music in the default Music folder then this won't be a problem. The program works great under the KISS (Keep It Simple Stupid) method but if Boom wants to be a 5-star program than it needs to first properly detect drives and then be able to scan your drives for music.
