I don't know if Silversun Pickups feel like a Smashing Pumpkins update just because of Brian Aubert's Corganesque singing voice, or if there are other reasons.
The other thing I noticed when thinking about "Lazy Eye" at greater length is that the main guitar line has a certain quality to it because the main melody (such as it is) is played on one string with the one below it open, and some part of the guitar line is echoed on the bass, which I'd probably be able to identify as a certain kind of chord inversion if it hadn't been 10 years since my last music theory class.
The point is, this happens in a lot of songs I like, including Collective Soul's "Shine" and, most notably, "Everlong." In fact, the more I think about it, the more comfortable I am dropping an "Everlong" comp on "Lazy Eye," and if you're looking for a reason to like a song, sounding like "Everlong" is a pretty good one.
