Cover art for My Song lyrics by Jerry Cantrell

This song is much more than likely told from Layne Staley's point of view. The last years of Layne's life he isolated himself and talked to almost no one. In an interview Layne did he said he wasn't friends with any of the members of AIC anymore. I'm guessing the actual lyrics are about how even before layne staley's wife died from drug related problems that layne had "lost his soul" and it just got worse after she died. If you look at the music video it illustrates Staley perfectly.
