These are classics and pretty easy. They were some of the 1st I learned to play and they are all pretty easy, even though only 1 has two "picks".

Dead easy to learn and everyone likes it. You can't go wrong with anything from Muddy Waters

Boom Boom by John Lee Hooker.

This is a blast to play and one of coolest blues songs out there. And it's pretty quick to learn. A bit harder than Baby Please Don't Go, but still pretty straightforward.

Smokestack Lightning - Howling Wolf

Very cool song to play along to.

Have fun, there are so many cool blues songs out there that are great for beginners.

PS: you mentioned songs in your title which is why I gave you songs. If you want a catalogue of go to licks - Jeff McErlain has a video course available of some of the most common riffs in blues. It is not on this site but on Truefire. Its called "Blues Guitar Fakebook V2". It will give you all kinds of stuff to have in your kit bag of goodies.
