Mobile content provider Zingy has struck exclusive licensing agreements with Kanye West and the estate of Aaliyah to offer unique ringtones, wallpaper images and other content to mobile phones.

Under the agreement with Aaliyah LLC, Zingy will have exclusive rights to previously unreleased content by the late singer. This includes an unreleased version of "Ave Maria," marking the first time a new Aaliyah track has been released as a ringtone first. A portion of all proceeds from the deal will go to the Aaliyah Memorial Funds, a non-profit organization supporting research for Alzheimer's, AIDS and breast cancer.

The deal with West includes exclusive ringtones, voicemail greetings, voice ringback tones, screensavers and wallpapers.

Zingy's network of carriers and media partners include America Online, Boost Mobile, Cingular, Microsoft MSN, MTV on Virgin Mobile, Nextel, Sprint PCS and T-Mobile.

Exclusive ringtones are the latest strategy mobile-content providers are utilizing to further monetize the mobile-music craze. Others exclusive licensing deals include InfoSpace with Lucacris, Virgin Mobile with Ashanti and Ja Rule, and Dwango Wireles with Styles P and Sheek Louch of Lox and D-Block. In addition, mobile content provider Blingtones recently launched a wireless "label" to create custom ringtone music, with such hip-hop producers as Q-Tip, Rockwilder, Denuan Porter and Salaam Remi.
