Digital music distribution service INgrooves has scored a fresh investment from Shamrock Capital Growth Fund.

While the amount of the investment is undisclosed, INgrooves' new capitalization reduces Universal Music Group Distribution's (UMGD) stake in the company to that of minority shareholder, along with Shamrock. INgrooves says it will use the fresh injection of capital to expand into the digital distribution of eBooks and movies, and will also look to make strategic acquisitions in the digital music space.

UMGD first invested in INgrooves in March of 2008. The exact amount at the time was not disclosed, but sources say it gave UMGD a majority stake in the company.

Additionally, INgrooves is further expanding its distribution agreement with UMGD to include all North American online retailers. After originally handling digital distribution duties for the label's Fontana independent distribution arm, as well as for such distributed labels as Hollywood Records, Concord and Big Machine, INgrooves began distributing content to North American mobile retailers for all of universal Music Group's major labels in August 2009.

INgroove's ONE Digital technology is the platform providing the digital distribution services. The company also works directly with artists like Thievery Corporation, Spinal Tap, Dolly Parton and Tila Tequila. Additionally, it provides marketing, promotion and synch licensing support.
