Shortly after he passed away I took a deep dive into his music catalog and I was so impressed with some of the songs that had never become big hits. His voice was so pure and his tone was so amazing. I think one of my favorite songs of his is "As". I also love that live version of Elton John's Don't let the sun go down on me. It's iconic.
That is true, you can find some really great tunes in his catalog and some different styles too. I really like that Elton John duet too, one of their great live appearances.
