Nokia's Ovi Music software is extremely poor and prone to crashing. What its probably doing, which it does th first time you install and run it, is add your music to its library which it takes HOURS to do and updates you badly on its progress. If you've got lots of music on your PC, leave it to run overnight and come back to it! Its that bad!
not for mac :/
Has anyone got OVI music player to work on Windows 7 ?
