How to get your iPhone to only update music in iTunes?

So basically, when you plug in your iPhone to the computer and click the "sync" button, how do you get it to ONLY update the music? It takes too long these days "upgrading" apps, etc. I just want it to upgrade the music, like my iPod.

This is what you do and you are going to be confused.plug you iPhone into the computer. Then open i tunesm then click on the iphone on the left side and it is going to take you to the summary then at the top you will see tabs that say photos music apps etc.well click on the music tab and check the box that says sync music to iphone the you go to the others like photos and uncheck the box that says sync photos uncheck all the boxes except mucic then when you get done click sync/apply and you will have only music on your phone
