Before the music catalog expansion, Amazon Prime members could access up to two million songs to stream through a simple search, and download songs for offline listening with no internet service.One user tweeted at Amazon Help asking for a partial refund because she lost all of the music that she purchased prior to the update.Another user tweeted that the platform is in "absolute shambles" after his daughter's Amazon echo smart speaker started playing random songs on shuffle.Amazon expanded its music catalog to capitalize on an increased demand for a wider music selection among current members, Jamil Ghani, vice president of Amazon Prime, told the Wall Street Journal.Launched in 2007, Amazon Music jumped from 2 million to more than 68 million users globally, which is 10% of the total music streaming market, according to data from Earthweb."
