ps/
I always considered J River the ultimate music organizer regardless of price. MusicBee is very close but still needs support for a few features. May I ask, what was the reason for migrating to MusicBee (its been some time now since I used JRiver and I may not remember correctly comparing it to MusicBee)?
I was using J River before MB, and I rechecked it a couple of months ago, to see how it had evolved.
As a PC user, I have to say that River didn't evolve last two years. I remark: 'as a PC user'. River focused in his MediaCenter side, and has become an amazingly good program for the living room TV.
For PC, MB is better and more featured right now.
Besides that, the only thing I miss from River is how fast it was...
