My main Audio Player for many years has been, and will remain, foobar, but there are some times when I just want a simple "load'n'play" type of player. An application that comes very close is Billy. It's a fantastic little app that fits in with my preferences in software design i.e. standard controls, no skins, etc. However, it only supports MP3, WAV, OGG, & FLAC and it also doesn't display or use tags. Unfortunately, my audio collection comprises many more formats than that and I tag files like a man possessed. So, with that in mind, I've always wanted to write my own simple player. A good friend and I wrapped the BASS audio engine in AutoHotkey and I've written a player called Trout.
