As an accessibility note, the following links use the same link text  
to different URLs. See the following quote noting, "Link text should  
be meaningful enough to make sense when read out of context -- either  
on its own or as part of a sequence of links."

<li><a rel="acquire" href="0810_40_st.mp3">Download Now</a></li>
<li><a rel="acquire" href="0900_40_st.mp3">Download Now</a></li>
<li><a rel="acquire" href="1800_40_st.mp3">Download Now</a></li>

WCAG 1.0 Guideline 13. Provide clear navigation mechanisms.
http://www.w3.org/TR/WAI-WEBCONTENT/#gl-facilitate-navigation

13.1 Clearly identify the target of each link. [Priority 2] Link text  
should be meaningful enough to make sense when read out of context --  
either on its own or as part of a sequence of links. Link text should  
also be terse. For example, in HTML, write "Information about version  
4.3" instead of "click here". In addition to clear link text, content  
developers may further clarify the target of a link with an  
informative link title (e.g., in HTML, the "title" attribute).

The ideal change (would suggest recommended best option on the wiki):
<li><a rel="acquire" href="0810_40_st.mp3">Download Foo</a></li>
<li><a rel="acquire" href="0900_40_st.mp3">Download Bar</a></li>
<li><a rel="acquire" href="1800_40_st.mp3">Download Bar</a></li>

The minimum acceptable change to conform with WCAG 1.0:
<li><a rel="acquire" href="0810_40_st.mp3" title="Download  
Foo">Download Now</a></li>
<li><a rel="acquire" href="0900_40_st.mp3" title="Download  
Bar">Download Now</a></li>
<li><a rel="acquire" href="1800_40_st.mp3" title="Download  
Baz">Download Now</a></li>


By contrast, the following redundant links with the same URL are  
fine. No known problems.

<li><a href="http://downloads.bbc...today/rss.xml">Add to RSS</a>
<li><a href="http://downloads.bbc...today/rss.xml">Add to RSS</a>
<li><a href="http://downloads.bbc...today/rss.xml">Add to RSS</a>
