Those themes are great tweetytunes, and they do cater to all skill levels. The only thing about it would be the "Theme". I don't want to be stuck with a specific theme I really don't care for. If the theme went greek or western/sci-fi, I would probably pass as I don't really care for those at this time.

I would rather stick with a theme thats a bit closer to my liking. Catering to all skill levels is great, sticking a "theme" with that kinda sucks, but thats just my opinion.

Lest stick with themes we can choose our selves.
