We Wanna Rock

Only tangentially related but awesome regardless.

Power metal has always been about heroes and their deeds, but I'm intrigued by the number of songs that present metal itself as something innately heroic.  Songs like Freedom Call's "Metal Invasion" and Sabaton's "Masters of the World" immediately leap to mind, but I'm sure there are countless other examples.  It makes me think back to the metal of the 80s.  Back then, it was all about how you wanted to rock and everybody else wanted to stop you.   I don't think Twisted Sister ever wrote a song that wasn't about rocking despite opposition, and Quiet Riot's classic anthem "Metal Health"... well, I think that one speaks for itself.  At a time like the early 80s when metal was still mostly marginalized it made sense for the genre to write these kinds of battle hymns.  Why do you guys think there's been a resurgence?  Or did these songs never really go away, and I'm just really noticing them now?  Is it a response to the way mainstream music has been swinging further and further into electronic territory, making the rockers feel like they need to fight back for their genre again?  Or is it just an indication of community and solidarity, something metal fans have always prided themselves on?  Also, if you can think of any good songs that fit this category please drop a link in the comments box.
