You'll get more out of your favorite songs if you know the lyrics - or at least, you'll stop singing the wrong lyrics and looking like an idiot.
If you're a big iTunes user, then you'll need DesktopLyrics to deliver lyrics directly to your desktop as songs play without any effort on your part. However, the lyrics are delivered in a Window that doesn't automatically appear on top of everything else so it can remain hidden. It would have been useful if the developers had somehow added an option to set the DesktopLyrics window on top but as things are, you'll have to minmize other windows to see the lyrics.
DesktopLyrics can also be a bit hit and miss as regards the lyrics it selects. Usually, you'll get the right song but occasionally it will either select something completely wrong or worse, nothing at all, leaving you with just a blank box. It seems that Desktop Lyrics doesn't use a wide range of databases to retrieve info which is why this occurs.
There are probably better lyric finders out there although DesktopLyrics is fine for anyone with a pretty mainstream music collection who doesn't mind minimizing windows to see it.
