Non-MP3 Codecs?

Vanth Dreadstar asks: "While MP3 is okay, I have begun researching other codecs that would be suitable for my home music use. Lossy codecs such as Ogg Vorbis, AAC, and MPC all seem to have promise, not to mention the lossless codecs such as Shorten (otherwise known as .SHN), LPAC, and FLAC. I would like to know what non-MP3 codecs people are using out there, and why."
