It's a nice program, functional in all normal applications. It is cross-platform: windows, mac and linux. It it based off of the Mozilla codebase. It supports some not so well known codecs right out of the box (FLAC, [OGG] Vorbis, WavPack).
However is too much of a resource hog for my tastes. In Windows it uses about ~140MB when idle. I wish it supported CUE sheets, but that can be added later on.
An interesting concept nonetheless. Alternate media players found
