Spotify plans to raise prices later this year in the US to help cover the cost of the 15 hours of audiobooks per month that they added last year, Bloomberg reports. They also report that Spotify will add a new basic tier with no audiobook hours for $10.99 a month. (That’s the current price for the premium plan that does include audiobooks.) Bloomberg says Spotify will raise prices $1 a month for individual plans and $2 a month for family/multi-user plans in five markets by the end of April, including the UK, Australia, and Pakistan.
