Really great site. Tab sites for been terrible for too long. This is a refreshing change from the popups, popovers, and audio ads that plague the existing tab/chord sites.
Kudos. The presentation is pretty good. I've had a similar idea rattling around in my head for a few years, but haven't had the time to build it... There's a major problem with all these sites that has yet to be solved. What that is is left as an exercise for the reader. :)
Thanks so much for the comment. I am hoping to monetize the site through both affiliate programs and advertisements. While the ads will be minimal, I strongly encourage our users to support the artists they enjoy by purchasing music through our affiliates.
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/ .
