In order to post this song from an album I purchased from the iTunes Store, I had to illegally download a different DRM-free copy. Had I pirated the album in the first place, I could have skipped that step.
This is stupid.
Now, the Amazon MP3 Store exists and has a massive, 100% DRM-free catalog of well-priced music. It’s better than the iTunes Store in every way: more-universal format, high bitrate, much larger selection (compared to the DRM-free “iTunes Plus”), and (usually) lower prices.
I’ll never buy music with DRM again.
