Share Music Between Smartphones With DoubleTwist And NFC – But For How Long?

You have to give the folks at DoubleTwist a pat on the back adding innovative features to their music player. Over the last several weeks they announced an upgrade that adds AirPlay support to the DoubleTwist music player, and at Google I/O conference they announced Near Field Communication (NFC) based MP3 file sharing between Android phones. Unfortunately, while I like how DoubleTwist is utilizing NFC, I am afraid that MP3 sharing might not withstand possible legal challenges from the music recording industry.

DoubleTwist is using NFC to establish the initial handshake between Android phones, then initiates the transfer of the MP3 file via Bluetooth or WiFi. In a video that DoubleTwist posted on YouTube, you can see how the process works, you simply tap the two phones that have a NFC chip. Right now, the only Android phone that has NFC is the Samsung Nexus S.

You might recall that Microsoft has a similar file sharing capability with the Zune, with the ability to send a music file from Zune to another over WiFi. The difference is that Microsoft’s solution includes Digital Rights Management that restricts the playback of the song on the receiving Zune to three plays or three days, whichever comes first. DoubleTwist does not mention any restrictions in their press release on how long the file can stay on the receiving device, or how long it can be played.

The version of DoubleTwist that has music sharing via NFC is currently in the Android Market, so if you are interested in trying the transfer capability out, provided you have access to two Nexus S phones, get it while you can.
