Some of you might have noticed that Apple introduced a new and improved iPod Nano, and some other iPod hardware. Apart from the hardware, they also released iTunes 8.
No subscription model for the music, but (apart from some other improvements) they added a Genius function. The Genius analyzes your music library, and makes suggestions on the music your playing. Cool feature since it finds/suggests songs with the same mood, but there's room for improvement.
The following screenshot shows a overview of the 'Forty Licks' album of the Rolling Stones. As you might notice, the Genius in iTunes recommend that I seem to miss. I can buy these songs on the right. Notice the missing songs and the ones I marked in yellow.... Okay, one of them is spelled wrong (Jumping instead of Jumpin'), but the others are correctly spelled.
This doesn't only occur on the album of the Stones. It occurs on almost every album/song I play.
Is Apple trying to earn an extra buck? Or is there a vacancy for a real Genius? Anyway, I'd love to have this feature on my iPod.
