Is there a simple way to download all of my iTunes music to my iPhone?

I have iTunes Match and I recently switched to a 128gb iPhone 6, therefore I have enough room to store all of my music. Because I have Match, it is all stored in the cloud and I can access it over a data connection on my phone. When I plug my phone into my computer, there's no option to sync all of my music. Is there a simple way to do this, or do I have go go through thousands of albums and songs and download them individually?

You can use iphone transfer software to copy Apps, Contacts, Songs, Videos, Photos, Playlist, Games, etc between iphone and computer. Here's the one I used to use
