I had never heard the Papa Roach song, but just youtubed it and listened. I grew up with Social D. and am a fan, but was not a huge fan of the I Was Wrong record.
I didn't find that much of a similarity. I think they start on the same chord, but the progression is different albiet slightly. Plus the Papa Roach lead guitar player riffs those lines over it, which adds a different melodic flavor to it.
You know Mike Ness's voice as soon as you here it, it's unique and is Social D's identity. The Papa Roach singer, not so much. I guess the similarity would be that sort of reflective, lyrical content where you say, "when I was a boy, blah, blah, blah". Pretty cliche, IMO.
What are you doing listening to Papa Roach, Reality? Did you lose a bet
