Shazam is doubling down on what it does best with its latest update: Recognizing songs when your memory (or pop cultural knowhow) fails you. And, for the first time, the app now highlights a search feature on its main page, which lets you dig for more information about songs and artists. The goal, naturally, is to convince you to stay within Shazam rather than hopping over to the web for music research. In my brief testing, the new Shazam app recognized songs from television and radio in a few seconds -- at times it even found a result in under a second. It feels significantly faster than previous versions of the app, which sometimes took over five seconds to lock onto a song. That's not a huge difference, but given that Shazam has been around for years (it was one of the first killer apps back when the iPhone's App Store launched in 2008), it needs to keep improving to keep up with competitors like Soundhound.
