Certain classical music are sublime. It is the closest thing to sublimity, if you disagree, but then again, we'd argue even more xD

'Pop music' and 'popular music' of the current generation, if it didn't exist would just provide less culture. However if we never had music, we'd be missing out on a lot of emotive expression.

Your question is interesting: if we removed all forms of music, would other categories of expression be removed? What about poetry that followed certain rhythm? Etc? We'd miss out on a lot. I'm not sure how much, as it's not causally traceable what effect music had on us, but such a though shouldn't be so quickly dismissed, in my opinion.
