Correct, the pirated music library was before they exited the closed Alpha.

No, that's what they ran on when the general public could join on a referral basis. They called that "beta".

The technology was already proven, i.e. The Pirate Bay and other torrent networks had already been a success for years. What Spotify likely aimed to show was that they could grow very fast and that their growth was too good to just shut down, like the entertainment industry tried to do with TPB.

After they took in the entertainment oligarchs they cut out the warez and substituted with licensed material.

Not sure if it was called "beta" or "alpha" and "closed" is of course up to interpretation, but it was indeed by invitation. Swedish law at the time (still?) had a clause about permitting sharing copyrighted material within a limited circle, which I know Spotify engineers referred to as somewhat legitimising it. I also know for a fact that once the invite-only stage ended there was a major purge of content and I lost about half of my playlist content, which was the end of me having music "in the cloud". Still, this is nearly twenty years ago, so my memory could be foggy.

		When I first started using Spotify, a lot of the tracks in my playlists had titles like "Pearl Jam - Even Flow_128_mp3_encoded_by_SHiLlaZZ". Always made me chuckle, it looked like they had copied half of their catalogue from the pirate bay. It took them a few years to clean that up.

		Yes, when the entertainment industry came onboard they immediately made the service much worse. I reacted the same way you did. IIRC, 2008, a little less than twenty years.
