SoundHound, a sound search company, says its SoundHound Player now offers free, unlimited LiveLyrics in addition to one-tap sharing in version 4.2 on iPhone, iPad and iPod touch devices.

SoundHound offers built-in, two-way integration with a user’s iTunes library. You can double tap any line of lyrics to fast-forward or rewind a track. What’s more, you can look up SoundHound’s artist bios, videos, and top songs for iTunes tracks.  

SoundHound Player is available by downloading the SoundHound app and tapping the player icon. Both the SoundHound (free) and SoundHound Infinity apps on iOS include the SoundHound Player.
