From Mike's blog:
This is "Issho Ni," the Linkin Park song we contributed to www.downloadtodonate.org. I saw a bunch of comments that: 1.) you thought it should have been structured in a different way because you wanted more "action" earlier in the song, and 2.) you thought there should have been vocals. I'll tell you what: you guys edit it, add vocals, sample it, do whatever you like--I'll let you finish the song. The vocals don't have to be about Japan, they can be about whatever. Sing, rap, rearrange, remix, write new material, whatever....and I'll post the best versions I hear up here on www.mikeshinoda.com.
