>>107I understand the point of compression, but there is nothing good about listening to MP3s.
Compared to FLAC/wav (and lossless music in general) MP3 is objectively inferior and a pain to hear. Why would you want to hear a version of a song that's inferior and loses its touch? The only acceptable time to keep MP3 copies is when you can't buy or find any copy of the song except in MP3 320 CBR.
Worse is when you hear music via youtube. The music from a YT video is severely inferior to the lossless version for listening because of compression. This is 1990 anymore; you can easily get a good HDD for a cheap price. Don't tell me you're one of those guys that uses SSDs for storage? You can see that OP runs his entire collection that has more than a million songs in the highest quality formats (SACD is 5-10x FLAC in size), and they only take up 15TB of space.
8TB WD Reds cost about $180, so you literally have no excuse for preferring MP3s over FLAC rips except for being poor. Being poor is a personal choice, but please don't attempt to convince others to follow the blind (or deaf in this case).
If you aren't listening to the highest quality of audio or lossless, then you don't really have good ears.
