I believe it was DRM-free.
Ovi Music Store
(which like iTunes Store for Apple) has DRM free
mp3 music files. Ovi Music Store continues working normally.
Ovi Music Unlimited
(OMU) is a service sold with certain phones, like N8-00 OMU. It won't be sold in most countries anymore but will still continue in certain (like China and India). OMU has DRM protected
music files. With OMU you get to download as much music as you want for one year. Obviously the record companies didn't let the music be downloaded DRM free.
