The present and future of blink-182's sound is a mixture between Untitled blink, +44, and AVA. As more music is created, the lines will become more and more blurred.
Pointless to say it's an AVA or +44 song. It's the music blink would've been creating after Untitled.
Fucking this. In the AVA DVD, Tom did say the material for AVA's first album were meant for the new blink record post-untitled. So...everyone STFU. It's just a natural progression for them.
