ReDigi argued that the process of uploading a lawfully bought music file to the Internet for sale through ReDigi's service was not a reproduction under the Copyright Act, because the file never existed in two places simultaneously. Under ReDigi's uploading architecture, as pieces of the music file are uploaded by the seller to ReDigi's servers, the very same pieces are erased from the seller's own hard drive, and scans are performed to ensure no other copies exist on the seller's computer. However, the court did not find ReDigi's argument persuasive. Instead, the court reasoned that the plain text of the Copyright Act made it clear that a copyright holder's right of reproduction is infringed "when a copyrighted work is fixed in a new material object." The court referred to the definition of "sound recordings" under Section 106(1) of the Copyright Act, which are "works that result from the fixation of a series of musical, spoken, or other sounds."
