Music Notes: Preview six Green Day tracks, shaking up The Shins, tours tours tours

- Green Day are streaming six songs from the upcoming 21st Century Breakdown here. The songs were originally previewed during a segment from L.A. radio station KROQ's Kevin and Bean Show. [GreenDay.com]

- Whoa! Some major changes for The Shins: keyboardist Marty Crandall and drummer Jesse Sandoval are no longer in the band and there's a new Shins album in the works. (For those who are curious, no it does not seem like Crandall's exit has anything to do with the domestic abuse issues that popped up around the time he was dating former America's Next Top Model contestant Elyse Sewell). [Pitchfork]

- A jazz-influenced track by Iggy Pop, "King of the Dogs," was released digitally yesterday, and can also be heard here. The track will appear on June 2's Préliminaires. [Stereogum]

- Listen to a new Beastie Boys track, "Lee Majors Come Again," here. [SPIN]

- Asobi Seksu have extended their US tour by adding dates in Oklahoma, Missouri, Illinois, Ohio and New York. [NME]

- And Peaches has extended her North American tour. [NME]

- Kylie Minogue is also apparently going to embark on her first (mini) North American tour. [Prefix Mag]
