Yeah, it's gotten to the point that I don't visit lyrics sites unless I know and trust them (several are listed toward the top of the FAQ). I don't know of any that have installed trojans, but I've come across many that have attempted to install spyware or other unwelcome software on my computer, or flood me with popups and porn. If you do a Google search for lyrics, you may want to view the lyrics from the "Cached" link from Google, instead of going to the site.
