There's a lot of stuff in here that I'm not familiar with.....I grew up in the early 80's, so I'm stuck in the Maiden, Priest, Sabbath, Ozzy + Dio Solo also ( I'm old I know...).....I do like Metallica and Megadeth a lot but for the most part, the rest is heavier than what I like.....I have a hard time enjoying death , speed or thrash Metal....there's some good riffs and hooks, but if I can't clearly here the lyrics, it doesn't work for me.
I enjoy my metal with some melodies which explains why I love Iron Maiden...the 3 guitars attack since 2000 is awesome. The newer Judas Priest is much heavier than it was in the 80's but it still kicks ass !
