How to play Apple Music and Radio (Beats 1) on iTunes?

I've updated to Yosemite 10.10.4 but I can't find a way to listen Beats 1 on my Mac...

Solution 1:

You need iTunes 12.2 - presumably will be out any minute now…

Update 07:30 GMT 1st July. OS X 10.10.4 iTunes 12.2 & iOS 8.4 all now available & successfully installed here.

Solution 2:

Apple Music require iTunes 12.2, which is not included in Yosemite 10.10.4 so, soon, Apple should release another update exclusively for iTunes where there should be a button to play Apple Music.

You can get that update from the iTunes menu - select Check for Updates...

If that update isn't rolled out or available, you can listen here:
