The most often overlooked, but technically best, music player of the late 90's was Kojofol. It's a shame it was never released as open source, but I'm fairly sure it couldn't be. The author had no license for the patented audio compression codecs it used, and it even contained an mostly unknown variant called "Astrid AAC". It's the last bit that has always had me fascinated, and no, it's not AAC as you know it. It was actually a variant of the VQF format with some MPEG-ish bits thrown in there for fun. It always sounded just gorgeous compared to other codecs at equivalent bit rates/sizes. I have a copy of Kojofol around here somewhere along with some old "Astrid AAC" formatted files. I've always thought about reverse engineering it, but there's really no point when you'd just end up in a lawsuit.
