In my opinion, the original Hotel California album by the Eagles was, quite simply, a masterpiece.  I don't use that term often but the quality of the songs, the way they were arranged so that they flowed into each other, the harmony of the group, the way that the songs seemed as if they were written just for the person who sang the lead on them; all of these made this album the quintessential album that reflected the peak of music in 1976.  No album ever matched it and few albums have maintained the ability to transcend the generations the way Hotel California has.
