i thought kretz did every guitar part for trippin' though? wouldnt dean be credited too for the solo? like between the lines, it credits dean for the solo but says robert did everything else
In all previous records the guy who came up with the riff usually got the credit for the whole song. Unglued, for instance, is credited to Scott even though Dean wrote the solo and Rob wrote some of the of the other bits.
What happened with Trippin, I believe, is that Kretz wrote the entire song except for the melody and solo. If you listen to the album, there's a rythm track under the solo that's nearly identical to the first 2 verses. I doubt they even knew where the solo was going to go until after Scott came up with the melody. So I think Kretz came up with the riff, the verses and the chorus as well as the bassline and drums, they handed that to Scott who came up with the melody and the lyrics, and then finally Dean wrote the solo while they were recording. But that just speculation.
