It is my opinion that you cannot be a Rock Snob without simultaneously being a Music Geek. It is an impossibility. If, like myself, you qualify as a music geek or rock snob, you must see this website. Imagine Bill James as a music fan instead of a baseball fan.
Henrik Franzon, a Swedish music fan with too much time on his hands gives us Acclaimed Music, a site you must spend a few minutes perusing. It is fabulously geeky and comprehensive in its analysis of the best reviewed albums and songs of all times (you can even download spreadsheets- oooh).
By the way, according to his calculation, Pet Sounds is the greatest album of all time- a fact I have know for a number of years.
Here is his mathematical analysis of the greatest albums of all time* (his spreadsheet has 3000 of them).
1. Beach Boys- Pet Sounds
2. Beatles- Revolver
3. Nivana- Nevermind
4. The Velvet Underground and Nico- self titled
5. Beatles- Sgt. Pepper's Lonely Hearts Club Band
6. Rolling Stone- Exile on Main Street
7. Bob Dylan- Blond on Blond
8. Marvin Gaye- What's Going On
9. Sex Pistols- Never mind the bullocks, Here's the Sex Pistols
10. The Clash- London Calling
(my Top 10 has 5 of these albums... 1. Pet Sounds/ 2. What's Going On/ 5. Revolver/ 7. Sgt. Pepper/ 10. London Calling)
He also gives us the Top 3000 songs of all time, as well as yearly analysis. Like a donut to the mouth of Homer is this site to me.
*as expected, everything is skewed to the 60s and 70s.
btw- the rest of my Top 10 (as of today) is 3. Abbey Road/ 4. The Joshua Tree/ 6. OK Computer / 8. Miseducation of Lauren Hill/ 9. Automatic for the People (these are Rock Albums, saving myself the trouble of fitting in Miles Davis and John Coltrane)
