You're so Vain !
The only Carley Simon song I like Rooster already stole :p I think she is beautiful and has an amazing voice but I'm not a big fan of her music or songs.
I like many her songs. Maybe my favorite is Carly Simon - Nobody Does It Better. By the way I recommend to listen such songs with good audio system. For example you can buy good subwoofer for affordable price for example from these best deals on amazon prime day(click here). It will really boost your audio quality!
