"We can see a continued positive trend, and that is very exciting," said Per Sundin at Universal Music Sweden.
Sundin is referring to the development of the Swedish music market to date in 2010, after a 2009 which signalled a break in the negative trend with total revenues climbing in real terms for the first time since 2002.
While digital sales accounted for the greatest part of the increase, CD and vinyl remain popular and also recorded gains.
Income from so-called streaming climbed by a whopping 438 percent to 65 million kronor ($8.24 million), which a large part coming from Spotify.
Per Sundin expects over 25 percent of sales to come from digital sources in 2010, in comparison with 16 percent in 2009. He confirmed that "a large part" of the digital money comes from Spotify.
"Spotify has been incredibly successful and attracted even more paying customers, who pay 99 kronor per month," said Sundin.
He pointed out that Apple's iTunes and Nokia's equivalent have also shown positive sales development, with Universal expecting further alternatives to come onto the market.
"We are testing subscription models, advertising-funded models... We are trying everything at the moment as we want the consumer to decide how music should be consumed."
Rival firm EMI has also reported that digital revenues are on the increase. Stefan Blom at EMI forecasts that digital revenues will account for around 20 percent of sales in 2010.
"But I want to underline, that when we talk about streaming it is not only Spotify. There are in fact other up and coming services, and YouTube also accounts for a significant proportion of listeners and watchers, Blom said.
Stefan Blom at the same time pointed out that Spotify is starting to become a very important income source for the sector, thanks to the continual increase in the number of paying users.
"It is growing month by month. This means that future prospects are very good, for us and for the artists," he said.
