It might have been better in the '80s, but when I heard Public Enemy No.1, I had a cringeworthy reaction to how bad that song was :x
I don't know, Megadeth have never really synced for me, it's either his vocals or just the overall sound of their songs that I just don't like. I mean yeah I like some classic songs, but even then....I feel like they shouldn't even be part of the Big 4, along with Slayer...bands like Exodus and Overkill seem to deserve that tag more. But now a days everyone's doing great, especially Exodus and Overkill that it's nothing to fret over, as they're finally getting their due.
