Query: R.E.M. as it's most political ... and groovy !!!

If you want to start listening to R.E.M. you should probably start with Out Of Time, but Document stands as the best ROCK album the band has done (read: not including Automatic For The People). "It's The End Of The World..." has an unresistable groove to it, while "The One I Love" and "King Of Birds" show a bit more sentimental side of the band. The anthemic "Finest Worksong" and the horn-ridden "Exhuming McCarthy" are also spectacular. Plus, have any of you noticed how much "Lightning Hopkins" resembles the style of the present-day Red hot Chili Peppers !?! Who's plagiating who, then? But the most notable change are the lyrics, which have taken a much more political features on this album, due to the Reagan era depression. There aren't really a weak song on this album, so in the end this rates as one of the finest records of it's decade and it's makers.
