You can download it, but you get better quality, and support the artist by getting DVD copies in a store, because alot of these are converted and formmatted to a lower quality to play on the web.
Yep, I'm the dullest there can be. Shame on my family, shame on me, shame on my cow. I miss the good old days where copyrighting wasn't as frequent as it is now. A lot of good videos got taken down... yep. Sure do miss those. One day I'll be favoriting a video, and the next day it's removed.
