Of the respondents who claimed some awareness of DRM, 61% believed it affected the rights of the music consumer to hear their music on different platforms, 38% classified it as simply a nuisance and 39% also expressed concerns over privacy. However, 63% agreed with the aim of DRM (to protect copyrighted music from illegal file sharing), showing that the problems they have with DRM are how it affects legitimate consumers.
However, DRM does not protect music from file-sharing at all, as fully ripped albums will still appear (almost all the time sourced from CDs) regardless of DRM - a fact pointed out by Steve Jobs earlier this year in an open letter to the music industry.
