Typical newbie experience, downloads stuff from a random website he found on google.com. Use fmhy or rentry to find what you need. Stop blaming yourself, things like this is what many newbies go through before they become like Bartholomew Roberts.
I don't think you can download premium streams with ytdlp if you don't have a premium subscription. Also the default stream for me using Metrolist on Android (custom YTM Client) is 145-210Kbps OPUS audio which is high res enough for my daily listening.
No, I don't think it's worth it because I checked rsload and v4.3.0 is avaliable there. DDL there are not speed limited. The version on Rutracker is older, v3.5.4 .
Same here, ytm rvx extended. What I like so much more than back on spotify are the recommended songs in the autoplay list. Spotify's algorithm just doesn't click with my taste.
Just checked on rsload.net and the lastest they have is 2020.1.3 . Though it says Shareware which is confusing, isn't it a paid app?. Then checking in the underground section on ru-board there is a whole discussion about later cracked versions of this app... you can take a look at that yourself.
Good.
