They cannot claim loss of revenue for songs you can no longer purchase through them, that's absurd. Imagine going to court saying potential customers would have maybe purchased a song pack, but didn't because they gambled on them not renewing the licensing for it 10 years later. Do you think about what you say, before you say it? If they cared for that revenue, they'd renew the licenses, but they've moved on to rocksmith+. Besides, assumptions don't have to be made. Someone from the website could ask UBISOFT their position on this instead.
As for insults, I treat people how they treat me, you're welcome. You definitely didn't respond to my question in a respectful manner. And again, if you'd read I would gladly purchase the songs I am missing if they were available through steam but obviously you can't any longer. What does that have to do with "absolving me from purchasing more songs"?
I am aware there are tons of songs here to play other than the ones I speak of and I am grateful for all the creators that shared them here. They have the time to learn this, I do not as I have a family and a full time job that takes most of my time.
