Are you sick and tired (like me) when you click on a  iTunes web link like this one and it opens up iTunes on your computer? Well, here’s a how to stop this from opening iTunes every time you click a iTunes web link:

Note: This is for Mac OS X users only.

1. Create any text file on your desktop
2. Change the file name to: change.itms
3. Confirm the file extension change
4. Get Info about the change.itms file by selecting it and hitting Command+I or just right-click and click on “Get Info”
5. Click on the arrow next to “Open with:” and you’ll see iTunes.app is selected as the default (this is what you want to change)
6. Click the pull down menu and select “Other” and then navigate to Safari, enable “All Applications”, then click “Add” and “Change All”

Now, after doing all that, I recommend that you relaunch Safari so you know these changes will take effect.
