John Mayer - Shadow Days

Mayer broke up with Jennifer Aniston in March 2009, after dating her for ten months. He continued to retain strong feelings for the actress, and its been suggested that the singer penned this as a "goodbye letter" to his former girlfriend. A source told US Weekly: "'Shadow Days' is about Jen. It really took him a long time to get over her. He really loved her a lot. He wrote the song as a farewell letter knowing [Jen] would hear it. Ultimately he's done a lot of self reflection though and he realizes they weren't right for each other."
