UPDATED: iTunes In Cloud Might Not Recognize 80% Of Your Music, Says Expert [Exclusive]


UPDATE: I totally screwed this one up. When my contact, TuneUp founder Raza Zaidi, told me iTunes in the cloud has only 20% of the all the music listed in Gracenote’s big database of music, I interpreted it to mean that the upcoming iTunes Match service would mirror only a fraction of most music libraries. What I failed to realize was that 20% of music in iTunes represents the most popular 20%. The remaining 80% is all the music in the long tail. So when Apple rolls out iTunes Match in the fall, it will indeed likely mirror most music libraries, just as Apple claims. In a clarifying note, Zaidi says matches will likely be 95% or higher. In addition, the Get Album Artwork feature in iTunes isn’t powered by Gracenote, as the post implies. Sorry for the mistakes. Teach me to post before my morning coffee.

When iTunes Match goes live in September, Apple promises to instantaneously match any of the tracks in your iTunes library to the iCloud… as long as it already has your music in its mega music library. What Apple hasn’t said is that as much of 80% of your music might not be recognized by iTunes Match… and the only way to get that music into the iCloud will be to spend days manually uploading gigabytes at a time.

How To Check If iTunes Match Will Recognize All Your MP3s [How To]


One of the big questions about Apple’s upcoming iTunes Match is how the online music service will handle songs acquired from non-standard sources, like analog LPs, or yes, file-sharing networks.

Coming this fall, iTunes Match will scan your iTunes library and make available in the cloud all the songs you’ve purchased online or ripped from CDs.

But Apple hasn’t explained what will happen with songs encoded from sources like tapes or LPs; or those couple of tracks you accidentally downloaded from a file-sharing network and forgot to delete. Will iTunes Match reject these songs or make them available?

In theory, the system should recognize most digitzed music. Apple has explicitly said it will not discriminate based on source, and someone likely ripped the songs from CD before sharing them with the world.

We’ve found a way for you to check how iTunes Match will treat your music library before Apple makes it public.
