This move may benefit the company prior to the sale. Apple Insider posted on their website that "The unusual method of stock sale will allow the company to go public without needing any additional funding to do so prior to the sale."
However, as similar to Google's unusual method of selling stocks, this is not the same case as it's not identical. According to Bloomberg, "Google's IPO period was similar, but not identical. The search engine giant took a hybrid approach to its initial offering, and issued over 14 million new shares in 2004, followed by 5.4 million sold by investors at an $85 per share offering price."
It is worth noting though that Spotify has a pending lawsuit against Wixen, a music rights management company. This might or might not have an effect on the initial public offering. According to Apple Insider, "Wixen's suit alleges that a $43 million settlement that Spotify agreed to pay to settle a 2015 class action suit was insufficient, and is seeking $1.6 billion dollars to put things right." In addition, they also said that "Wixen in a lawsuit filed in California federal court claims Spotify failed to obtain proper licenses to distribute tens of thousands of songs, according to The Hollywood Reporter. The publisher seeks damages of at least $1.6 billion plus injunctive relief."
