Really? The fact that you hear the rendition of the people who created the song has no additional value to you?
Like, let's assume for a second that JLB's vocals were superior to Freddie's (which they really aren't). Even in that case, it would have to be a LOT better to counteract the fact that they're just mimicking somebody else's work.
Well, DT's version of the Queen medley does have a bit of a heavier edge to it. Maybe it's the mix, of the instruments, or the recording equipment, whatever it is, it's still very enjoyable, and when I'm in the mood for something with a little more oomph to it, I definitely prefer DT's version of that particular song. Same with Stargazer.
But honestly, with Pink Floyd, I think Roger Waters is one of the most unremarkable singers ever. Like, he's not bad, he's not good, there are some songs where he has a bit of a pretty cool swagger to his style, but all in all, I generally find him pretty boring to listen to. Floyd's instrumentation were pretty great, though. But even then, I don't think Dark Side is that amazing of an album. The Wall IMO is far superior. There are still some interesting moments on Dark Side, but between not being my favorite album, and Roger Waters not being a vocalist I'm all that fond of, given the choice, I enjoy DT's version of Dark Side a lot more.
With Number of the Beast, it really depends on my mood. But sometimes I simply feel like listening to JLB doing Maiden. Or Deep Purple, or whatever else we got on the Uncovered CD. I'm not that big of a fan of Ozzy either (I like him, but not that much), so in most cases, I'd rather listen to DT's version of Diary of a Madman.
When it comes to Master of Puppets though... Yeah, no... James just can't do any kind of justice to James Hetfield's particular style, haha.
Or at least, what we ended up getting on the official bootleg, he didn't pull it off very well at all. But I'm not a very big fan of Metallica, or their Master of Puppets album, so I rare listen to either version.
But anyway, yeah, in most cases, I really enjoy their covers, but yeah, it would be cool if they dould have reorchestrated them a little. The problem is that DT is a very versatile band when it comes to styles, so doing the covers in their original style, it's not like I can even say, "Well, that's not like DT do play that soft, or that heavy," because they do traverse both ends of the spectrum, and do acoustic stuff, and piano ballads, etc. So it's not like having a band with a very narrow and particular sound like Disturbed doing their style's versions of these songs.
