They're all kindof heavily layered guitar and piano with a backing that sounds like a drum machine. Gone are the guitar driven riffs and bursts of frenzied verses that made GNR good to begin with. They've been replaced with continuous (and for the most part incomprehensible) droneing from Axl and constant noise for music. At least Axls voice sounds better than he did at the MTV awards, although I think his screeching days are gone for good.
Of those 3 songs, I liked I.R.S. the best, since it at least has a remotely singable chorus. I've heard from people who liked The Blues and I'm not in a great position to judge, since the version I have is fairly low quality, but it's very ballady and un-GNR like. T.W.A.T. (or There was a Time) sortof sounds like a lower quality Estranged (not that Estranged was all that great to begin with) without Slash's melody lines. Robin Frink or whatever the new guy's name is simply can't hold a candle to Slash's playing.
The biggest problem is that Axl simply doesn't seem to have any energy left. There's no driving guitar or hard rockers in the bunch. There'll probably be some attempt at a few harder songs on the actual album, but from what I've heard Axl's content to sit back and write meandering, sappy, artsy pieces that simply aren't GNR. I'm hoping the final album will be decent just as much as the rest of you, but I don't see it happening.
