I listened to all the Megadeth songs posted and I'm sorry guys, they suck compared to Metallica. The song Washington Is Next has great guitar but Mustaine's voice just ruins the song and the lyrics are spotty at best. Rhe song 1000 Times Goodbye is a beta simp song that has no business being on a metal album. The other songs are just incomplete. Great guitar but shitty lyrics and vocals. Metallica's worst song is better than Megadeth's best. There is a reason why Metallica has sold millions and millions of albums and Megadeth has sold far far less.
A lot of people feel this way. To me, Metallica went mainstream after And Justice For All. The song "One" really caught a lot of peoples attention. Metallica's first album Kill 'em All was essentially their best album when it comes to metal, it was more like Megadeth in many eyes and rightfully so considering Dave had much influence over it. Metallica was able to soften up over the years and get more attention. Megadeth was always raw and raspy, many people do not like Dave's voice. But the people that like Megadeth LOVE it.
Nothing made by either band after 1994 was worth a shit, maybe a few one off songs. Metallica's best albums are their first two. I even make an argument with people that their Black album is shit too. I hated Enter Sandman and Sad but True, however people loved those songs. I can't even listen to that album. My Friend of Misery is my favorite or maybe Unforgiven. Metallica changed over the years and stayed main stream-ish.
I still listen to Kill em All and Ride the Lightning all the time, but that's about it.
