Well if you listen to it, all band members are in it,so yeah..all of them did sth. And Lockjaw is basically Mike and Rob but it's a LINKIN PARK track..
1)it's NOT music released by LP. it's music with the contribution of one member of Linkin Park,
Mike mostly, but it's other artist's work. There is no Linkin Park in the songwritting..it's LP related but not Linkin Park. I dont know what they consider as Linkin Park music, but since they're a band of six members, what they release as a whole is their music. Even if only 2 members write a song,
they all participate if they release it, even with only giving their opinion about it, because belonging to the band means that whoever had the original idea,when a song gets out of the studio,it's the band's work... (team spirit)
2)Well of course having an extra project pushes you back,I didnt complain about that.After all it gave us a new LP song which we wouldnt have managed to listen to otherwise.
also,Mike said: "Secondly, I said we’d “release music more often".
By sayin "we" I understand Linkin Park.So the LPUS, New Divide,Not Alone and We Made it is new music. The other projects he mentioned, dont count as releasing music more often,cause it's not LP. Now if he mentioned it to excuse himself for the delay of the album,I dont think there's any need to do that..
