The music streaming giant had previously imposed restrictions on the amount of hours users could listen to music each month, whilst those who paid their monthly subscription for its Premium service enjoyed ad-free listening free from restriction.
The move follows Spotify's announcement last month that users could now use its mobile phone service on iOS and Android for free, which in the past had required a subscription. The only catch is that listeners cannot select the exact song they'd like to listen to, but must shuffle through their playlist. The company reported a four fold increase in the number of Spotify app downloads in the wake of the news.
The free mobile music service puts Spotify head-to-head with Apple's iTunes Radio, which is currently only available in the US but is expected to launch in the UK and other English-speaking countries by early 2014.
In a blog post on Spotify's website, a spokesman said: "In the past, we had to restrict your listening time to some hours a month once a 6-month unlimited grace period had passed. But now, if you haven’t noticed, there’s no more time limit if you are using Spotify for free.
"We have removed these caps completely across all platforms – you can listen to your favourite songs as many times as you like, for as long as you want."
With more than 24 million active users in 55 countries worldwide, Spotify is one of the world's largest music streaming services. However internet radio service Pandora boasts around 72.4 million active listeners and more than 200 million registered users.
