Only in America. The shear obsession with comparing music is just astounding. Charts are commerce NOT music. I do not care how many people buy your song, I want to know who is buying your album. Chart are not an indicator of the quality of music (they rarely are). Look at all the Grammy Awards for Album of the year (another comparison of art), most of those albums were not successful commercially.

It is only spectacularly stupid person who say that Rihanna is a better musician than Sade because she has more number one songs in America than Sade does.
