At the beginning of this year, Rdio boss Anthony Bay claimed he wanted his company to "be everywhere," seeing a low (compared with Spotify and Pandora) penetration rate in the US as an opportunity for growth. Bay also mentioned expanding into pre-installed Rdio-ready devices in cars, as well as internet television.

So in the interest of continued expansion, Rdio have launched a very cheap, $3.99-per-month subscription offering titled Rdio Select. This differs from Rdio Unlimited – the equivalent competition for Spotify Premium – in that Select will allow users to download up to 25 tracks per day that can be played offline, with the added option to swap any of these tracks once per day. Twenty five tracks a day doesn't sound too bad at all.

What's more is that Rdio are rolling this out in India for a very, very cheap 60 rupees (around 94 cents) a month, called by a company spokesperson "the most inexpensive offering ever to hit India from any music streaming company."

In an article last December, TIME reported that "India represents the next big growth opportunity for smartphone makers" – 900 million of their 1.2 billion population own a mobile subscription, but only around 110-120 of those own smart phones. Just as Rdio saw the potential growth for their service in the US (a survey found only 1% of smartphone users had the app downloaded), they're seeing it in India, too.

It arrives after Rdio acquired Indian streaming service Dhingana at the start of this year; but they're up against rival streaming apps Gaana and Saavn, as well as widespread music piracy.

Currently, Rdio Select is available in the US, Canada, Australia, New Zealand and South Africa, with more launches planned for the future.
