This is just something that I feel like is an abosolute truth. Both bands are incredibally innovative, and have some of the best, catchiest, most well written songs of all time. I've never heard anyone make the comparison before, but I think it's totally apt. Weezer is the modern day Beatles :)
If Weezer is the modern day beatles, We wouldn't talk about how bad half of Weezer's new albums are. Unlike Weezer, the Beatles had more than 2/3 crazy ass albums that you could listen to front to back without any filler tracks.
