Into The Lungs of Hell (the original version not the shitty remixed and remastered version).
My Last Words (the original version not the shitty remixed and remastered version).
Basically the original version of all Megadeth songs. I dislike the remixed, re-recorded and remastered songs Mustaine released a few years back. I think he did the whole catalogue from killing right up to System. The remasters do not have the same quality sound to them the original releases have. The "new" versions of each album sound weaker in the music. The anger and speed just isn't there in the so-called new versions. Do yourselfs a favour and go find the originals. Boycott the Mustaine abominations that are the remastered albums. I read somewhere that he too some flak for the remasters. Rightly so, he tried to fix what wasn't broken. He re-recorded a lot of the guitar work for the older songs and mixed it in with the old songs. It shows as well. It's like a lightweight Megadeth the new remastered albums.
