How does Rivers Cuomo write for other people when he needs help writing his own stuff now a days? Expect a safe by the numbers pop album with little to no creativity and a lot of co written radio crap. What pisses me off about this band is that unlike about 90% of neon pop bands they actually have a semblance of musical talent and had potential at one point.
Whatever your opinion is on Weezer's music, Rivers has publicly said that he just started trying out co-writing. He had always written his old stuff and wanted to try something new and fresh.
While some people may not like the product of his writing sessions, you can't say it's a bad thing for the guy to try something new after working a certain way for years and years. As for All Time Low; they definitely have the opportunity to learn a thing or two about writing songs from all these artists and producers, which will help them somewhere down the line.
