Cheesy lyrics don't bother me. Generally I don't even care about lyrics, to the extent that I can even tolerate most of Linkin Park. Music and vocal quality are much more important to me. A major exception that I can think of (decent sounding song that I can't tolerate because of the lyrics) is Breaking Benjamin's "Diary of Jane," which is so obnoxiously inane and immature that I can't listen to it. And it used to be on the radio way too much.
