Launched on iOS and Android in 2011, Musixmatch scans your tracks stored locally on your device or lets you stream a track online, whilst displaying the lyrics live in a karaoke style. Musixmatch has since been brought to Windows, Windows Phone, and even Google Glass. You can also access the service within YouTube (through Chrome) and Spotify.
Musixmatch have recently unveiled their new site, which brings the service to the desktop. Users can now discuss specific songs, and search, edit, sync or even translate existing lyrics.
