This is pretty cool, but there's at least one piece of data you're throwing out from your scraped pages.

Compare The White Stripes' "Offend in Every Way" tab on your site (http://cleantab.com/offend-in-every-way-guitar-tab/white-str...) and the scraped site (http://www.xguitar.com/guitar-tabs/white_stripes/white_blood...). xguitar is telling you where the chord changes happen by placing the chord name over the lyrics (e.g., on the first line, you play a G when singing "plan").

Also, on your blog pages, the top header links to http://blog.cleantab.com/blog/ , which is a 404. You want to link to http://blog.cleantab.com/ .
