During the time I had the 1st generation iPhone, I decided to jailbreak it, and came across the TuneWiki app, I liked it, then I had a problem with my phone and had to restore it thus no more TuneWiki. You may be asking what is TuneWiki, well, it’s a full featured music-related app that displays the lyrics of the current song that’s playing. That’s not the best part. When it displays the lyrics, it follows along with the song.
TuneWiki also has a bunch of other features such as music videos, streaming radio via Shoutcast, real-time top 50 charts, interactive music maps and more. It should be said that TuneWiki is free, and it’s another one of those apps that should be on every iPhone because it offers something more for your music.

I also should let you know that according to TUAW:
It should be noted that TuneWiki has a direct licensing deal with Universal EMI, Sony, and about 16,000 publishers in 1800 groups including Warner (via the Harry Fox Agency) as well as deals in Greece, Israel, Spain, Germany, Turkey, and so forth. Every attempt has been made to license this lyric use world wide. Amnon Sarig, TuneWiki founder, told TUAW that he’s worked hard on securing these world wide licensing agreements to ensure that TuneWiki has rights to display lyrics wherever it is used. "No one else has worldwide exploitation rights," he told us. "I’ve been in the licensing business for 11 years and as far as I know, the only other application on App store that exploits lyrics legally has their licenses limited to the United States."
