AvA AND +44 were both turds. Neither of those two compared to the glory of Box Car Racer or the Transplants, in terms of side projects that is.
I would take +44 over Box Car and the 2nd Transplants album (the first one was f-ing awesome). Better songwriting, imo.
I'm not going to lie, Blink-182 was one of my favorite bands in high school. It got me into first, punk rock, and more importantly, branching out a little from the standard fair heard over the air waves in the radio hell known as northern Iowa. Because of them I started listening to older punk bands (like The Descendents), and eventually just started broadening my entire sonic palatte, as now I listen to a wider range of music (classic rock, grunge, alt-country, jam bands, etc).
To be honest, I really don't care much for some of Blink's music anymore. There are some classic songs I still like, but some that are just way too aimed at a specifically high school audience, and I can't really relate anymore. Makes me feel like Wooderson, from Dazed and Confused.
All that said, I hope they're getting back together because they miss making music together (and not for the $), and that their new album keeps moving in the direction (maturity) that their last record went. They really had some balls on that record, as far as expanding what they were trying to do.
