Middle School was an odd time for me, especially when I think about music, because it was around 6~7th grade something clicked in my head and I finally began to develop musical tastes that diverged from what was popular with my peers. The most important album was Portrait of an American Family, but Countdown to Extinction was a pretty big one as well, and it was my gateway album for metal in general; it's still probably my favorite Megadeth album.
