Songs like these, suggestions - classic rock?

Trying to find songs similar to these two. Not just in the same genre but compositionally similar.... Or if you have any suggestions you think I'll like, but I'd like to keep close to these. Tried Spotify and wasn't pleased with the suggestions. Ok:

"I love you more than you'll ever know" by Blood Sweat & Tears

"Since I've been loving you" by Led Zeppelin

Coincidentally both these songs have love in them but that's not necessary.

But if you listen to these songs you'll immediately notice a connection. A strong bluesy and soulful apparent lead guitar. Very obvious in Jimmy Page's solos. Amazing. I've listened to a lot of blues and haven't stumbled upon anything that really stands out. Really would like to expand upon these songs here.

Thanks
