Audio Formats - Comparing FLAC vs. MP3 @320

So I wanted to download a collection of music and found that the collection in question can be obtained in FLAC or in MP3 @320, I decided to download both and to compare them.

Are you also trying to figure which is better for you to keep?

Well, let's start with the obvoius:
MP3 @320: is a lossy format meaning some of the sounds will be omitted from the original.
FLAC: is lossless meaning it is identical 1:1 to the original.

The problem is that a song on FLAC will take about x2 x3 more storage than MP3 @320

So most of us are quality driven people - we don't care it takes more space and we sure as hell don't want to loose or forfeit any sounds!!

But honestly, I have a very good hearing and I listen to music few times a week - I could not tell the diffrence... I tried very hard to justify a 43mb FLAC encoded song vs. the 15mb MP3 @320.
But they were identical!

Conclusions:

Listening to Music = MP3 @320
I promise you, your audio expirence will not be any less.
Processing Music = FLAC
Use it only if planning to process the music, analyse it or remix it in order to create somthing new.
