RealNetworks sold over one million songs (at a loss) in one week since announcing Harmony, the company said today.

The company said "more than one million songs were sold in the first week of the Freedom of Choice campaign". Real's 'campaign' - which has attracted a deluge of criticism - means Real is trying to sell more songs to Windows users, as its Harmony technology does not support other chosen platforms.

Real also claims its 49-cent downloads resulted in the "busiest week ever" for Rhapsody subscriptions.

Apple has not yet responded to Real's initiative to make songs acquired through its service compatible with iPods, but has threatened legal action.
