No this is a problem xoxo can not be used in a table this way produces
invalid markup

you would have to mark your table up like this:

<ol class="xoxo">
<tr><th axis="track">Song A</th><td axis="acquire">download</td></tr>
<tr><th axis="track">Song B</th><td axis="acquire">download</td></tr>
<tr><th axis="track">Song C</th><td axis="acquire">download</td></tr>
<tr><th axis="track">Song C</th><td axis="acquire">download</td></tr>

notice I left out border="3" use CSS to do this.

really you are supposed to give each axis property an id attribute too

I don't know if you would lose or gain any semantics using tables 

Tables are nothing that microformats have got round to exploring (Yet)
