Ability to merge genre's

[sudanberry]

When you have 6 genres that are vitually the same thing, it would be nice to drag one to the other and change all the tags automatically. WMP does this.

You can select all songs you want to have the same genre, and use the Edit option to change only the Genre field for all of them.
This is slightly more work than drag & drop, but it's possible already.
