I'm just going to throw my opinion into the blender of society.
Every era of music has a different style, the 40's had Big Band, the 50's had Rock & Roll, the 60's & 70's were groovy, the 80's had their synths and hair bands, the 90's were the 90's, etc. I personally do not find this current era's style appealing. I feel that many of the bands today sound much too similar and that there has been an overall decline in creativity. Now don't get me wrong, there are a few new songs that I do enjoy, but many of them emulate the style of an earlier musical era, which I do suppose ties into the decline in creativity that I mentioned earlier.
What it really boils down to is personal preference. I find my enjoyment in the oldies, but you may find it elsewhere. No one has truly got a "wrong" preference I suppose, although there is some pretty tasteless stuff out there. It's just whatever man, you do what you do, but don't force it upon others.
