Well, this past month on youtube I was watching Sea of Tranquility, which is a music talk page hosted by Pete Pardo, and he talks about all sorts of stuff. I recommend subscribing to the page if you haven't. Well, last month, for each day, he mentioned a favorite album from the 70s in the Hard Rock & Metal genres. He picked some really good stuff, and I followed along and included stuff that I liked. Wasn't easy, but I think I got some good stuff, even though there's others that I could've mentioned as well. Here's my list of albums, and these aren't really ranked, just stuff I like:
