Led Zeppelin - Since I've Been Loving You Lyrics Meaning

Since I've Been Loving You is track four of side one on the album Led Zeppelin III. It is a slow blues. It is a slow blues along a similar vein to Fleetwod Mac's Dreams. It was influenced, partly, by the Moby Grape song Never and became a live favourite very, very quickly.

Lyrically the song follows a popular form theme that is often present in both blues music and popular music. The theme of the man mistreated by his woman. The narrator has been working hard and making sacrifices for his woman but he receives nothing in return. This only leaves the man crying. The woman even commits adultery against him!

It's pretty much that simple.
