Oh, I like some of Opeth's songs. They can be really mellow which seems strange to me in the metal world. That's why I like them.
Hmmmm... the most masterful? That's a really hard question to answer.
There definitely are a few (and not all songs from the album, unfortunately):
Janis Joplin - I Got Dem Ol' Kozmic Blues Again Mama!
The Used - In Love and Death
