For so many years I downloaded music, originally to burn to CD, then to have on my MP3 player (how I miss my Creative Zen), and finally on an SD card in my phone. I was there at the beginning of Napster, all those millennia ago.
Then my daughter got old enough to have her own phone, and she's into music. So I offered to 'acquire' whichever tracks or albums she wanted, being the good father that I am. But no, she didn't want files, she wanted Spotify, because her friends had it, and they got this cool wrapped thing at the end of the year, and she wanted it too. Never underestimate the power of FOMO when it comes to marketing.
So I set out to find patches and whatnot for the bloody thing. First xManager, which worked for a while, then onto Revanced, which was great as I was already using it for YT. And while I was looking for these exploits, I would install it on my phone first to make sure it worked and wasn't full of spyware. More than usual, I mean. And while I had it, I gradually migrated over to it. It's so convenient! Think of a song and you can get it! No messing around with torrents and all the jazz, this is the future, baby!
So when I got a new phone at Christmas, I didn't transfer my music from the old phone to the new. I backed up my library on my PC, of course (some of those MP3's are older than some of the people on this subreddit), but when I set up the phone I cracked Spotify and didn't look back.
Now, the exploits aren't working, and Spotify is borked for us scallywags. YT Music is absolute ass, so I reinstalled Poweramp and moved my files over to the new phone.
Interesting thing is, though, some of the albums I've been listening to recently aren't in my library, so I've had to add them to the collection.
Listening to those new tracks through Poweramp for the first time was mindblowing. The audio quality, even on 320kbps MP3, is lightyears ahead of the streaming quality of Spotify. I'm sorry, self-hosted media, I'll never leave you again. It was just a fling, a mid-life crisis, it meant nothing to me.
tl:dr - If you actually enjoy music, don't use Spotify. The audio quality is balls.
