MP3 is a "lossy" format. It works by removing audio information that the human ear theoretically cannot hear, effectively "compressing" the file size by chopping off the high and low ends of the frequency spectrum. For modern, digitally produced electronic music, this loss is often negligible. However, for music recorded in the early 90s, which often relied on analog recording techniques and a blend of organic and synthetic sounds, this compression can flatten the soundstage.
For many listeners, MP3s or standard streaming are sufficient. However, for a soundtrack as layered as Hello Brother , the FLAC format is essential for several reasons: Hello Brother -1994 - FLAC-
If you own the original Hello Brother CD, consider ripping it to FLAC and sharing it in lossless communities. Preserve the sound of 1994 for the next generation. MP3 is a "lossy" format
