Sort artists by last name and find missing digital booklets

Kirk McElhearn | Aug. 26, 2013
In this grab bag, we answer questions about missing digital booklets, how to sort artists by last name, embedding album art in purchased files, and more.

This week's column is a grab bag, where I look at a number of interesting questions about Genius, sorting albums by an artist's last name, finding digital booklets in your iTunes library, and more.

Q: I use Genius quite often and wonder how it works. Is it similar to Pandora where music is analyzed and matched using computer algorithms, or is it "crowd sourced," based on matches done by other iTunes Genius users?

Also, why is Genius "unavailable" for certain songs? I'm not referring to obscure songs but songs such as "Sympathy for the Devil" and "You Can't Always Get What You Want" by The Rolling Stones, or "No Sugar Tonight" by The Guess Who. I've run into quite a few other songs for which Genius is unavailable in my 7000-plus track library.

iTunes' Genius feature is based on your music library and how it compares to the libraries of other Genius users. Apple has never officially explained the technology behind Genius, but an article in the MIT Technology Review cites a post made by an Apple engineer on Quora (which has since been removed) that said that information from a user's iTunes library is "folded into a larger database of users and songs."

Essentially, Genius looks at what's in your iTunes library and compares it with what's in other iTunes users' libraries. If you have, say, three songs by Lady Gaga and five by Luciano Pavarotti, and enough other users have the same distribution of songs, then you might see music from those two artists together in a Genius Mix or Genius Playlist.

While I find Genius Mixes to be dubious--perhaps my iTunes library is too eclectic--Genius playlists tend to group similar types of music.

As to why certain songs don't show Genius suggestions, I wish I knew. I can confirm that many Rolling Stones songs don't show Genius suggestions, as well as many well-known songs by the Grateful Dead, Lou Reed, The Cure, and others. Go figure.

Q: I downloaded an album from the iTunes Store that came with a digital booklet, but I can't seem to find it. It's not showing up with the album. How can I find where this digital booklet went?

Digital booklets you get from the iTunes Store are PDF files. They should be in your iTunes library together with the album, but sometimes this isn't the case. If you can't find it, you can make a smart playlist that will find all the PDFs in your iTunes library (whether they are digital booklets or books). Use the following condition: Kind is PDF Document.

If you want digital booklets to display with the music they describe, you need to set the Album, Artist, and Genre tags to be the same as their albums. (Select a digital booklet in iTunes, press Command-I, then make these changes in the Info tab of the window that displays.)
