You're kidding, right? They sound TOTALLY DIFFERENT. Even though Angels and Airwaves included some from Blink-182, they only think comparable was the voice. Maybe your abilities to hear are unsufficient.
But yeah, I'm glad to hear they're back together. I remember 6 years ago I went to one of their concerts, was a great time . Also, they're who really got me and my best friend to this day to be friends, was our similar taste in music, with our favorite band blink-182. I really have grown out of that kind of music since then, and I appreciate bands more for the music they create, then About 7 years later, we're still tight and we still like the same kind of music till this day .
Although I might of told my life story now and you didn't feel like reading that whole thing, I'm GLAD THEY'RE BACK TOGETHER.
Heh Angels and Airwaves and +44 have members from Blink so it's not that surprising they sound similar. I used to dislike Blink (Tom's voice was just annoying) but now I quite like a fair few of their songs. Tastes change! Not really into pop punk as a genre though
