I second this, but with a few things I wish I would have known:
- Before you hope on SoulSeek (with an application like Nicotine+), please study up on the etiquette - downloading someone's shared files without sharing any files that they can choose to download for their collection is called leeching, and while some people don't really care, a lot of SoulSeek users will get really angry if you do this because they're giving you their internet bandwidth for nothing in return.
- To share files, you have to port-forward; be sure to check your ISP's terms of service. I hear that as long as you're not using a huge amount of bandwidth, even stricter ISPs can be pretty lax on enforcing their anti-p2p rules, so you may be able to get away with the risk of breaking the terms of service. However, to truly reduce the risk, you should probably use a VPN.
Of course, there's a whole other ethics of piracy rant I have, but I'd rather not pull it out right now. The main time I used SoulSeek was to download a rip of a rare TMBG CD (like, not a single copy on Discogs and only 1 on eBay).


At least in the objective legal sense, it very much is in the eyes of the YouTube terms of service and the law of most jurisdictions with strong copyright protections.
There is a legal distinction between streaming on YouTube (normal TOS-compliant use) and downloading the video as a whole through a 3rd party tool (circumvention of copyright protection, and YouTube gets no ad revenue with the download), which is usage outside the TOS.
Now, I don’t really give a darn about following US* copyright law for a megacorporation’s sake^1^ and have gone ahead and downloaded from YouTube, but it’s still piracy in the legal sense. This is not intended as a criticism of your actions, just a legal nitpick.
*Obviously, not everyone here is American (good riddance); this is just my personal experience. 1: Especially considering Google’s breaking it all the time with their ML models in my opinion.
