Hé Maricusa,
Regarding lyrics:
There's many ways to adjust lyrics. For instance: in Main Player, right click in the Lyrics panel (if not visible, make it visible via 'Arrange Panels'.)
If you have lyrics in your clipboard: that should work ('Paste Clipboard Lyrics into Music File').
You can search for other lyrics. And you can tell MB where to look: in Edit/Edit Preferences/Tags (2) - Auto-tagging - Lyrics. (And you can install the 'Lyrics Reloaded' plugin to install more lyrics providers. And/or other plugins.)
Does that help?
