A study by the Martin Prosperity Institute assigned each metropolitan area in the United States a "Metro Music Index" according to the concentration of musicians and of businesses in the music industry. Ongoing studies are also incorporating online information from networks central to the music industry, such as MySpace.

The top 10 metro areas with the largest index are:
1. Nashville, TN
2. New York, NY
3. Los Angeles, CA
4. San Francisco, CA
5. Seattle, WA
6. Las Vegas, NV
7. Portland, OR
8. New Orleans, LA
9. Rochester, NY
10. Minneapolis/St. Paul, MN

I'd like to add "true/you/do" to the list, particularly from older songs.

Lulu, of course, is the TRUE masterpiece. Also, this chart hasn't quite exercised Master of Puppets to its fullest potential.
