At first, when I started with JRiver MC, I didn't want to use it as a tag editor. I'm not sure why. Maybe I thought it wouldn't be as good as a dedicated tool?
But then one day the light went on for me and I realized how simple, streamlined, and powerful the tag editor in MC was. After using it for a couple of days, I never even thought about using another tag editor.
Ditto for renaming and moving files. At first JRiver's Rename, Move, and Copy tool seemed weird and complicated and I didn't use it. Then I learned a little about it and WOW is it powerful! You can do renaming, moving, and copying with JRiver that's very sophisticated. It's a fantastic tool.
Someone said this in another thread and it bears repeating again and again: A lot of times, you'll want to do something with your music collection, and you'll go looking for a tool to help you do it. Then, when you dig into MC a little, you realize that MC can do it already. It just has such wide and deep functionality, that very, very few external tools are needed.
