Let me say this I have both apps. I loved SoundHound when the iPhone 4 came out because they updated it with retina display right away. I didn't really like the orange colors that much I'm more of a cooler color guy. Now that Shazam updated I can't help but love it more because it's a cooler color. I just wish they would take that stupid Encore thing off their app because it looks ridiculous. Which one do you like using more?
