Sgt Peppers - I had to, I had skipped the Beatles in earlier rounds waiting for this album.
London Calling - I'm surprised at how few votes it is getting. I feel like the t-shirt is more popular these days.
Moving Pictures - Very skilled musicians and Tom Sawer + Red Barchetta are just awesome.
Back in Black - Iconic. Google "Orchestra plays..." and it's still awesome.
Ten - peak grunge, anthems for several years.
It was very hard to pass up Metallica, Pink Floyd, Green Day, Chili Peppers, and Oasis. And even though they are lower on my personal ratings Black Sabbath, Eminem, Led Zepplin, and Public Enemy are obviously very strong contenders. This was the hardest one so far.
