The first, which came out last week, is the new single from Blink-182, the first with Matt Skiba (of Alkaline Trio) taking over Tom DeLonge's duties in the band. It comes from an album called California, which will be out on July 1. The song debuts at #18 on the Alternative Songs chart that came out today
The second was just released today and there is not a lot of information related to it. All I know is, it's a new Radiohead song. And it's good.
