Lyric sites are really bad. I am a gigging musician, and beleve me, my pc needs an enema after I update my lyrics book.
Y'all need to try Firefox. Every now and then I get a new-window popunder, and that's about it.
Also, I find it's generally better to not use the first few sites Google offers up, but to use a site that's towards the bottom half of the search page. The guys at the top are paying Google to be there, and tend to have more agressive "stuff" on their pages.
