Only super popular releases are shared now and have a semi-decent number of seeders. Back in 2005-2012, I could find any obscure album there. Now it's pretty much impossible to download a bunch of mp3 albums on a USB drive for my car.
Oh, man. I feel your pain. Quite recently I was unable to download a game, left alone music. It's pretty much impossible now. Of course, you can pay for the YouTube music premium may be the option, you can download the song an offline player is quite decent. But you can download come on come on turn the radio on common-common-turn-the-radio-on.mp3juices.red/ here for free
There are variety of music torrents still where you can find your favorite tracks. Note: The legality of music torrenting is a fine line. While it's not illegal to use torrents or download music through them, it is illegal to infringe on copyrights without explicit permissions from the copyright holders
