Woo. A "basic" lyrics searcher that can search different sites. Load the code in remotes and type /lyrics.

Instructions:

1) Input your song and artist for that song.
2) Select which site you want to search, then hit Go. That was hard.

According to what song you want lyrics for, you should try a different site. Usually, you'll get used to one specific site for your lyrics (like me). Here's a breakdown of what each site has:

azlyrics - an overall general lyrics site for stuff like pop and things on the radio.
lyricsbay - just another general one, so that you have two chances of finding what you want.
oldielyrics - use this for older artists, such as from the 70s and 80s, like donna summer, queen.. that kinda stuff.
plyrics - quite specialized, this. This site deals ONLY with punk music.
urbanlyrics - deals with R&B, Rap, Hip-Hop, Soul, Gospel and Soul music.
alivelyrics - another general site.

Extra stuff:
Last 50 searches - this was kind of an excuse to fill up space. But it's a nice little feature.
Auto-input for playing song - if you have a song playing in mIRC through /splay, the dialog will fill the artist and song name in the edit fields for you automatically.
Load/save lyrics - allows you to save/load lyrics so they can be quickly accessed on a later date or whatever.

..enjoy I guess.

Tested on 6.34 and 6.35.

Updates:
April 30th - added new site (alivelyrics.com)
