Bitlegging (v): Downloading copyright-protected digital music files from the net. As illegal as bootlegging, but the sound quality is better.

1999 (earliest)
MP3.com makes available free, legal MP3 files from artists wanting the exposure. Visit the music section www.mp3.com/music/. Of course, downloading a ripped-off version of, say, the All Saints' Never Ever is the digital equivalent of bootlegging (bitlegging?).
—John Graham-Cumming, “Living with the Net: Make your PC really sing,” The Guardian (London), March 11, 1999
Notes
American Dialect Society member Grant Barrett alerted me to this blend of bit and bootlegging.
