A friend of mine has Plumb's "candycoatedwaterdrops" album in MP3 128 kbps format. I have the same album but in FLAC, ripped directly from the original CD. We were comparing both formats and when we got to the 6th track (God-Shaped Hole) we noticed something really curious. In the FLAC version, at the beginning of the song we could clearly hear some kind of digital drum in low frequencies. In the mp3 version it was completely missing. Both songs are identical in time length and composition, except for that drum. My question is, could lousy MP3 compression suppress a clearly audible instrument like this? Unless there are two versions of the same song (I doubt that) this is a good example (apart from the obvious audio quality) to convince my friend that low-q mp3 sucks.
