Spark customers on some monthly plans will be able to continue streaming music on Spotify Premium for free through to 2018.
The two companies have agreed to extend their exclusive partnership for a further two years.
The global music giant partnered with Spark in February 2014, offering customers on some Spark plans access to Spotify Premium for free.
Spark Home Mobile & Business General Manager of Marketing, Clive Ormerod said its partnership with Spotify was an example of how the company could offer something different for customers.
"Our partnership with Spotify truly reflects our ongoing transformation from a traditional telco to a provider of the digital services that make the lives of our customers a little easier and richer every day.
