The forthcoming launch of Spotify in the US will see Americans get a proportionately better deal than us veterans in the UK, according to leaked documents.

According to a sign-up flow sent to TechCrunch, the Unlimited Spotify plan will cost $4.99 a month and the Premium service, with access to mobile music will cost $9.99 a month.

Although, on the surface, that sounds the same as our tariffs, the dollar-to-pound conversion means that US users will get Unlimited for £2.99 and Premium access, including mobile playback for just £5.99.

The leak also reveals that American users, like us, will get ad-funded free access to the service with a limited amount of plays per month.

Unconfirmed?

With the pricing seemingly in place, it can't be long until the service is launched across the pond.

Some reports claim record company deals are yet to be finalised, while others claim Spotify is waiting for Facebook to sort out the rumoured collaboration with the company.

After the story broke, Spotify's PR made a statement claiming that no actual prices have been confirmed yet, but we suspect that these will indeed be the launch prices.

The company says:"No details are set for the pricing or details of our US service yet – we're still testing a number of different options. We'll be sure to let you know when we have something to announce."

Google briefly re-opened the invite process for its new Google+ social network in order to double users during the initial trial period.

Following a phenomenal demand to join the new Facebook rival, Google closed invites last week, but late on Wednesday night members were once again allowed to invite their buddies to join.

The invite mechanism has now closed again, presumably after Google racked-up enough new users to double the population.

Last night engineering direct Dave Besbris posted on the Google+ site, explaining that the limited roll-out is to ensure that the network works properly and that bugs only affect a small amount of users.

Growing slowly

He said: "I wanted to take a moment to explain why we're growing the system slowly. First, we want to make sure our infrastructure scales so the service remains fast and reliable.

"Second, we want to ensure that bugs are fixed while there are still a relatively few people in the field trial.

"Things are going well with the systems right now so we feel comfortable enough to open up invites for a brief period.

"Our goal is to double the user base in the field trial. (Sorry, we're not giving details about how many folks are in the field trial yet)."

"So, in a few minutes, we'll open up invites again.We continue to throttle invites, so please don't mass invite folks as it won't work. If you invitea handfulof your most important friends and family you're much more likely to get these folks into our system."

Google has yet to reveal when a full public launch will take place.
