While a fraction the size of some larger stores, eMusic also claims to be growing at a much more accelerated rate than it has been in the past. The launch of Amazon MP3 has purportedly helped drive awareness of eMusic and is responsible for about 40 million of the company's total download statistics; since the September unveiling of its rival, eMusic has supplied roughly 7 million tracks per month.

The sales tally suggests a continued surge in sales of unprotected music, particularly for services that offer most if not all of their catalogs without DRM limits. While eMusic is one of the earliest such stores, Amazon has already reached second place among digital-only services despite higher per-song costs than eMusic and no current support for sales outside of the US. Its early success has largely been attributed to offering music from all four major labels without DRM.
