If you are in the habit of keeping good ID3 tags in your iTunes library, you can link in some useful information when you display a “Now playing” link in your posts.
I put the Amazon ASIN info in my comments field, so when I export my iTunes library with iTunes2html, the album links are there for interested buyers. So why not add that in here as well?
This in Preferences -> iTunes:
<em>now playing</em>: <strong>ˆt</strong>#a from the album ˆa#a#p by ˆp#p | <a href=”ˆk”>#kBuy it#k</a>
yields this:
now playing: There There (The Boney King Of Nowhere) from the album Hail To The Thief by Radiohead | Buy it
