Unlimited tagging is now here for everyone, so Shazam as much as you like. 

Hear a song you don't know? Shazam identifies it instantly - the 4th most downloaded App of all time. 

You can also:

• Save & listen again (with 30 sec preview)
• Buy tracks easily on iTunes
• Watch music videos, concerts and artist clips on YouTube
• Share music with your friends on Facebook and Twitter
• Learn the lyrics you thought you knew
• Discover new music from your Shazam Friends and Shazam Charts
• Find out when an artist is on tour or has a new album available
• Use it when you don’t have a signal

“Do you believe in magic? Maybe you will after trying Shazam – a jaw droppingly awesome music identifier. It has the uncanny ability to recognize the track and tell you everything about it” – Gizmodo

You can upgrade in the app with a few taps for no banner ads, and the incredible new LyricPlay experience: a full screen visualization of lyrics in time with the song you identified.

Notes:

*If you used Shazam on your current iPhone / iPod touch before November 9, 2009, you’re still entitled to unlimited usage.

*Shazam on the iPod Touch requires an external microphone for models without a camera.

*Previewing and buying music requires the iTunes music store in your country. Previews are courtesy of iTunes.

*Lyrics are available in the US, CA, UK, FR, IT, DE, ES, AU & NZ.

People who use Shazam on the new Android platform will simply be able to hold their devices back-to-back with that of their friends to share their favourite music, merchant offers and television tags – giving their friends access to music samples, coupons from advertisers, tour dates and other great information.
