Back when my son made it thru Navy Nuke school and was assigned to a sub, I thought what could I get him for Xmas. Once I decided on music, I started nonstop torrent downloading music for months. I gave it to him on a HD and they made him the sub's entertainment Petty Officer. I passed around my copy at work. That HD went thru gobs of people before I got it back. Since then I've downloaded mostly just movies. I have now around 27,000 songs and 4,000 movies. I very seldom download these days.
Thru years and years of torrent downloads, I've only had my hand slapped(warned) twice. And each time it was for things that my kids had downloaded.
Once my CDs were converted - Actually, ripping mp3s was not that hard, but all the pre-CD stuff was impossible - I still had Beach Boys and others on 8-track... So the LP, 8-track, and Cassette stuff was mostly what I went to replace... And then I started in on complete discographies... But once it was all complete, one of my music library software calculated that I could play music for for a crazy amount of time without repeat... 24/7 for some months, Crazy.
That's when I kinda backed off of it. I still have the legit stuff (I had purchased the media otherwise) laying around - and even that is somewhere around 40g. But the rest of it is largely discarded.
Movies, sorta the same thing... I mainly started a movie library to develop best practices for my clients - I had no idea how to manage such a gigantic library (weight) without the actual doing of it...
Most of it is gone now. I keep maybe 100g laying around in case the internet goes down, so I have some sort of entertainment. But for the most part, I find movies to be fairly juvenile anymore. Especially in the last decade. There are not many I could point to as being worthy of preserving.
One of these days I might get back into it, just to preserve what I consider to be worthy... I am heavy to westerns and Warner Brothers cartoons right now, with some major action flicks and sci-fi... But really not even all of them are worth the backup.
