Yeah, Napster was interesting. I found so many new bands through it, which I then went out and purchased more of those bands' music.
I recall when Pandora launched, and it was a year and a half of absolute bliss for me. I loved finding the new music and exploring in it. Then the RIAA and others lobbied for worst-case broadcast lawmaking AND bumped the streaming costs for internet to a degree that just about killed any independent, nascent, internet radio efforts. Meanwhile Last.fm (barf) was purchased by I think CBS and, UNFUCKINGSURPRISINGLY, had zero issues with international broadcast rights.
So, yeah, this was never about protecting their copyright so much as defending the status quo and limiting anyone else's new take on finding and accessing new music. Absolute territorialism at the pointy end of the sword of the law.
