Bad idea ... do you know what happens to my Brazilian
heavy metal when a site tries to play its background music though
the same PC speakers? It sounds worse than a bagpipe band playing
polkas! Unless you are selling music, demonstrating music, or
discussing music, leave sound files off your pages.

To improve your listings, get rid of the frames.
>now I have meta tags only in index.html.
>Should I put them in all pages?
Each page should have META tags that describe the individual page, but
>will it increase the possibility of users entering not from the main page?
Users can enter from any page they want to, provided they have the URL.
You have to design the site to make it look good from all entrances.
