Ever been shopping at the mall, dancing at the club, or eating dinner at a restaurant when suddenly you hear a cool song, but don't know what it's called? Rocket Mobile, developer and marketer of mobile phone software applications, has come up with the solution: Song IDentity. Song IDentity is among one of the many applications available through MetroPCS Communications. This is how it works:

Hold the phone up to the music source for 10 seconds. Once the sample is recorded, it's sent to a server for recognition. The results are sent back to your phone, including artist and song title. It also e-mails you with links to more information about the band and places to buy the CD or buy an MP3.

Other applications developed by Rocket Mobile are National Geographic Wallpapers (photos from the National Geographic Society's Image Collections), and the soon to be released iNDie Music (music selections from worldwide independent labels) and MobileMix! (a ringtone composer).

Song IDentity is available on Verizon Wireless, Alltel, Midwest Wireless, nTelos, and Western Wireless. For more information, read Wireless Week's report.
