OnMouseOver Event

I have a table with two columns and two rows in it. In the upper left corner, I
have a logo image for my company. In the top right column/cell, I have some
navigational stuff, no big deal. In the left cell in the 2nd row, I have a list
of anchors of different songs I am producing - something like this:

<A HREF="jamison.mp3">Jamison</A>
<A HREF="tlw.mp3">The Long Winter</A>
<A HREF="summer.mp3">It's Summertime</A>
....
....

The cell on the right, 2nd row is empty at the start.

On the 2nd row, 1st cell, where the anchors are, on a "mouse over" event, I'd
like to display song lyrics and information regarding the song in the right
cell, 2nd row as the user moves the mouse over a given anchor.

What is the best way for me to do this? There are a couple of things/issues I
can think of right away:

1) Let's say there are 20 anchors in the left column. Let's say that some of
the songs' lyrics are quite lengthy and extend past the height of the cell at
row 2, left column. How would the system know this in advance (this will make
more sense with question #2 below)? Perhaps tell it some type of maximum height
you know will never be reached or something?

2) To me it doesn't make a lot of sense to include all this text in the main
HTML file since a majority of the time, the user(s) will never move their mouse
across ALL the anchors, only one or two. Seems to me there should be some way
of "loading" them as soon as the mouse over event occurs.
