However, I am listening mostly to music from the last 5-10 years, so there is that.
It really depends on who you're listening to. For example, this LP and ones like it will reduce you to tears of joy on expensive headphones, and as you can see from the waveform nobody is telling amon tobin how to compress his tunes:
Especially check out the second track, which starts at around 6:40. Although that is obviously a 128 kbit/s preview stream. Get the CD.
I believe it started because people wanted their car stereo to sound like their home CD, so sound engineers started to over-emphasise the bass, to bias it for radio, which led to a vicious circle.
I can't listen to anything post 2000 on my very good home sound system because the bass is so over-emphasised.
