And why doesn't iTunes have a tagging feature, like everything else does, these days? Don't they know that sometimes I want to filter my music not by artist or genre, but by topic? I want to be able to find songs with the word ORANGE in the lyrics. I want to be able to tag songs based on how difficult it is to dance to, and on what dance(s) I would do when it's playing. I can tag photos in Flickr, web pages in Del.icio.us, and emails in Gmail. I can even tag to-do list items in Things and blog entries right here in Blogger (though I usually don't).
Apple had an idea of it a while back, I think. Their Mail program uses a tags-like system for email addresses. The Papers guys use the same system for searching Pubmed, though I haven't quite got the hang of it there.
I was using the comments field in iTunes for tags. It worked, somewhat, but there wasn't the kind of uniformity that tags really need. What if I spelled something wrong? And what if I tagged one song with "male" (as in, male vocalist), and another with "female" (likewise)? Whenever I would search for "male" I would also get "female", completely defeating the purpose.
I'm just complaining. But really, it would be helpful. I have a lot of music that I forget about because I can't label it properly. When I'm looking for specific categories of music, I have to rely on work-around ways to find it, and I usually end up picking songs I already know fit what I'm looking for, without trying new things.
