for each year the MP3 sits on your hard drive, it will lose roughly 12kbps, assuming you have SATA
Heard this can also vary depending on whether your SATA is 1.5/3/6 Gbits/sec as well as the age of the drive (platter spin speed and whatnot) - in general I recommend just keeping the “two in the bush one in the air” adage in mind. personally I like to have physical music, and then FLAC copies on my personal PC & mirrored onto my NAS!
Godspeed! :rat-salute:
