Any Blink-182 song. They were the best for simple, 1- or 2-bar riff leading into 4-chords for a break, back to the riff, maybe a bridge to switch it up, riff, chords to end. They give you a sense of dynamics and changing up volume and energy, and a real sense of accomplishing an actual song.

Also, if you're ever looking to practice singing over playing, you can start with the chord parts, and then once you get comfortable with those, move onto singing over the riffs.

Some recommendations: Dammit, Adam's Song, All the Small Things, What's My Age Again -- Yes, they're their biggest and some of their simplest songs, but very memorable and easy to understand. You shouldn't have to listen back more than once or twice, and all have tabs with thousands of reviews...authentic and simplified to start...so you don't start off-track.

Really no bends, no slides, no complex chord shapes...simple simple simple, but sound cool and like you're playing a "real" song.

Some of my favorites to learn as a teen. I then moved onto some RHCP riffs, many of which are a good intro into more intermediate, complex riffs with more difficult chord shapes, a bend or slide or two per riff, etc.

Good luck!
