I don't recall ever hearing rock music from your country. Not on your links, but I think "Crunch Time" really rocks! I liked it best of the 3 songs I listened to. I liked "Breaking the Mold" second best, and "Heavy Heart" (some interesting spring reverb on the intro) third best. They're all good though overall. I've never had anyone from Viet Nam review my music, so it would be cool if you checked out my music at this link (you'll probably prefer the second song):

Hey. Thanks for the comment. "Crunch time" is not my track. I heard it from a guy on here.
I actually don't listen to music in my country a lot so I'm more influenced by bands like Guns n' Roses or Iron Maiden etc.
I'll check out your song.
