Music-streaming company Spotify Ltd. has raised $526 million in a fundraising that values it at $8.53 billion, according to a person familiar with the matter, as investors bet it can fend off a new threat from Apple Inc. The fundraising attracted investment from a number of investment funds in Europe and the U.S. and included a $115 million investment from Nordic telecom operator TeliaSonera AB, which said the two companies would work together on areas such as media distribution, data analytics and advertising.
