The funny thing is, Apple had an iron grip on the music market because of DRM. If you wanted to license music for digital download, the music industry demanded DRM, and Apple had the only DRM consumers had any faith in. You couldn't use an alternative DRM scheme with iPods; FairPlay was Apple's proprietary technology and it was the only DRM iPods would recognize.
The music industry only caved on DRM specifically because they realized they had written Apple a blank check. Had Apple not had a long and storied history of trademark litigation from The Beatles' record label (also named Apple), they could have started directly signing artists themselves.
The difference between then and now with the Epic lawsuit is that iOS has no sideloading option. Going DRM-free meant you could sell music on iPods without paying Apple. For software, the closest equivalent would be webapps on iOS, but that usually entails rewriting significant parts of your app and losing access to certain functionality. You don't get push notifications, you can't access native UI so all your UI code has to be redeveloped to something worse, and so on.
