I didn't see anyone discussing this application anywhere, so i create this thread.
Tunewiki is a "Free, Self service lyrics-to-music playback synchronizing utility and related services. It opens your own music file, goes to the Internet to try to find lyrics via a simple search. When you listen to the music it shows the lyrics in step with the music."

You can install on our iPhone/iTouch through AppTapp under the Multimedia category.
This app is awesome, as stated above it searches for lyrics in their database and displays it on the screen while the song is playing.
Some lyrics are pre-synced, so it actually scrolls the lyrics as the song plays. If the lyrics are found but are not pre-synced you can sync the song an the lyrics by tapping on the album art while the song plays (easy). and sometimes (rarely) it'll say "Sorry, no lyrics, yet!" You can join the wiki and upload the lyrics.
I know that they have a Windows media player plug-in that lets you send the sync you created to the server, I'm trying to find out if the iPhone is sending the songs I'm syncing. Please share your experience with this awesomest app!
