SoundTracking – Although currently available for iOS 4 devices only, this music app tries to offer an all-in-one bundle based on the music soundtrack of your daily life -the tunes that add a splash of color to your routine. SoundTracking comes with a built-in music ID feature, which is the standalone product of many music apps out there (such as Shazam and SoundHound). But SoundTracking doesn’t stop there. The app includes geo-tagging music snippets and sharing these with your friends along with a photo of the track’s artist or album.

Want more? SoundTracking lets you check in to Foursquare when you post a soundtrack with a location, and you in turn can follow friends’ location based on their tagged songs and check ins. SoundTracking is ideal for the iPhone users who love sharing in general, and sharing what they’re doing and what they’re listening to in particular. This app is free which is, considering all the perks it offers, surprising to say the least. In other words, go ahead and download this wicked app ASAP while it’s free.
