The way I look at is, he plays guitar parts that a fun, and that in turn are fun to listen to. A lot of times I prefer a fun catchy guitar part or even In Pieces guitar compared to an 6 minute long Metallica solo or something. Yes a lot of solos are nice to listen to, especially the one Mike E has been doing but sometimes I just prefer stuff that sounds good. Sure, the solos are harder to do and more complex, but it doesn't always mean they are better to hear. That's just my opinion anyways.
