What is skiTunes you ask? Well, the main idea is to provide an alternative to iTunes that is as user-friendly as iTunes, but does not have iTunes' limitations and is 10x more powerful - Think iTunes Pro. When finished, it will be able to play many formats such as WMA, OGG, FLAC, TTA, and more. It will also have power-user features such as folder-based playlists, multiple libraries, tab browsing, and multiple iPod management. It is currently in earlier stages of development, and is not yet a viable iTunes eplacement, but I do encourage you to check it out.
