Viva la Internet: Albumlinernotes.com
Which is true; liner notes of yore list the nerdiest of details about a recording. Take for example, your download of Exile on Main Street by the Rolling Stones. You swear that's Dr. John singing and playing piano "Let It Loose." A couple of keystrokes later you've confirmed it. You'll also find out they had a dude named Amyl Nitrate playing marimbas on "Sweet Black Angel." That shit you won't find on Wiki.
Some liner notes have pretty sweet prose, too. Take for example the 3,000-word handjob rock critic Michael Phalen gives Steely Dan in the Aja liner notes. A key excerpt: "Rich with images of random violence, copulation, drug abuse, loitering with intent and other misdemeanors, this sociopathic jump tune is sure to become a classic zebra in the annals of Punkadelia." Eat your heart out, Pitchfork. They don't write like that any more.
Anyway, there are thousands of entries like that to waste time on. Internet, FTW.
