Frisson

A desktop audio player with a quad-colour e-ink screen, four keys and a thumb wheel. It will let you pick a letter to jump straight to an artist, album or song, so you never scroll through a long list.

It will also play FLAC files at up to 24-bit/96 kHz, higher quality than a CD. Some people get frisson, a chill or goose bumps on the neck, from music they love, and that slightly better fidelity can make it easier to feel.
