Yes - because the string is already delimited with double quotes.

What JavaScript? There is no JavaScript in the code you present here.

Don't put target="show" inside the href attribute. Check the created
HTML - you will hopefully see the error.
You define $htp as:
$htp="http://mroldies.net/index.php?tune=".$play." target=\"show\"";
But then you write:
echo "<a class='aplay' href='".$htp."' ...
So - expand this - it will become:
<a class='aplay'
href='http://mroldies.net/index.php?tune=$play target="show"'
Try to think about the problem - step by step. And not just put together
a bunch of code without caring for details!
If you put just the anchor attributes line by line the code also becomes
much easier to read. Also note that you can enclose double quotes in
single quotes (and vice versa) and there is absolutely no need to define
a separate variable to use an array value.
And finally: Either you have to make sure, that $playme[$play][3] does
not contain any "HTML stuff" or use htmlspecialchars() to encode/escape
special characters so they will be displayed properly.
Here a proposal how it should work (not checked - there may be typos):
<?php
foreach($numbers as $play) {
echo '<li>';
echo '<a';
echo ' class="aplay"';
echo ' href="http://mroldies.net/index.php?tune='.$play.'"';
echo ' target="show"';
echo ' data-src="http://mroldies.net/200/'.$playme[$play][4];
echo '">';
echo htmlspecialchars($playme[$play][3]);
echo '</a>';
echo '</li>';
}
?>
F'Up to comp.lang.php since this has nothing to do with JavaScript at all.
