Now that I'm done posting dank maymays, time to post something I actually listen to. Though I'd be glad to argue with you about the song you rated, since it's definitely not pop and definitely not on the radio.
Personally, I think Metallica is highly overrated. While they did bring metal into the mainstream, or at least helped a lot, their songs all sound the same. They chose to never evolve their music further, and opted to instead keep using the same sound that got them famous, and it remained that way for years after Ride the Lightning. Death Magnetic sounded the same as well, the only difference is that the quality was higher because of technology. 3/10
I listen to this guy Rhian Sheehan A LOT. He makes great ambient, melodic, orchestral type stuff. He went and began experimenting with more rhythmic elements recently, and for this song I think it turned out very well.
