Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I hope your will and testament are up to date, you are basically screwed.

Parents crying at the hole they put you down in the cemetery. Girls you knew, secretly confessing that they would have 'done you - together, at the same time' whilst eroding the earth with their tears. Boys from the same grade, sobbing wishing they were just like you, to get "those other girls back there". That mate of yours that always was a bit weird, who rocked up with his AK47 and 250 rounds of ammo "just in case".

FBI staking it all out, and waiting for them to disperse, so they can dig you up, and take your corpse to A51 and dissect you to see how many rings you have to determine your age, and if you have links to piratebay.

If you’re paranoid, you can convert the FLACs to WAV on an isolated computer (or VM), copy them and recompress them to FLAC or other formats. If there is a vulnerability in FLAC, it won’t persist through transcoding.

Should be ok if there is no bad vulnerability in the player you are using.

If you are paranoid, plug the files into virustotal.

Just use spotdl https://github.com/spotDL/spotify-downloader

No idea about the site, never heard of it. Pretty sure FLACs couldn't harm your PC (correct me if I'm wrong).

Buuuuuut if you're gonna download another FLAC from the internet I think it would be safer to get it from either doubledouble.top, the Slav Art Divolt channel, or just Soulseek like the other dude mentioned.

may have?

No.

For the next time, if you want .flacs, just use Soulseek.
