Ringtones Campaign Structure in Adwords

We know there a thousands of ringtones keywords we can use on a campaign.

I'm trying to promote a ringtones campaign, but there is a limit of 100 adgroups per campaign. Let's say I have 10000 artists name. How can I structure my campaign?

I have heard it is best to put 1 keyword per adgroup.

 

Multiple accounts in a my client center

 

Is manually the best way to build these 1000's of adgroups? I know there is software that can speed this up but with adwords you need quality pages for each seperate page...

 

You can have more than 100 ad groups in one campaign. I have one campaign that has over 1200 ad groups.
