I've tried every variation possible to add Shazam to the QuickLaunch icons I have set up but whenever I select Shazam from QuickLaunch nothing happens.
I think they will be correcting that issue in the next update. Shazam was released after QL was so I don't think they were able to make sure that app was compatible.
It's funny because when I go to add Shazam it even shows up in QuickLaunch and I type in the name I want to give it but it just doesn't work. I don't mind waiting though.
