Mp3/Tag Studio is shareware, and if you like it and want to keep using it after 30 days you should register it.
By doing this you will support the shareware concept and upcoming versions of the program. You will also get free updates of Mp3/Tag Studio forever, i.e. it's a lifetime license for only $19!
As soon as you register the program, that annoying advert window will go away forever and you will have your own name in the about box. You will also have the option to join the registered users mailing list, where you will get special info and news, and of course immediate notification of all future updates. If you later don't wish to receive this anymore you can easily unsubscribe yourself from it at any time.
If you can't afford to register the program but still want to keep it, it's ok, but in that case please click the banner everytime you use it, ok? :-)
So, now that you know all this, maybe you would like to register
right away? :-)
