The other day Andy mentioned it didn’t seem like I had many female artists on my iPod, which is accurate, but it got me wondering what my actual mix was, so I ran a couple of random sets of 25 and 100 songs, and it comes out to about 70% male vocals, 15% female, and 15% instrumental, with a slight edge on the female vocals vs instrumental pieces. Which seems backwards to me, but it’s occurred to me that the instrumental songs (primarily post-rock and various types of electronic music) are longer on average.
It also occurred to me, while manually counting, that this type of structured tagging and listening pattern/music analysis would be insanely addictive and potentially useful, but I don’t think that there’s anything out there that currently does anything like that, and certainly nothing integrated with your music library.
