Library Loading

[Maxcee57]

SORRY, but I can't find the answer to this!
How do I stop Winamp from loading my whole library into the playlist when I click on a song?
How can I get the song that is playing to be highlighted? When it goes to the next song it is not highlighted.
I have been using and looking at Winamp for years.I don't use very many controls as I don't know what the changes I make will do.
These are my only issues.
Thanks
