Between the 6-8sec mark this track can cause a lot of issues for low bitrates LAME mp3s - I used CBR 64kbps and it was easily ABX'able.

On 11 sec there's some 'crashing' coin-like sounds that are interesting. After about 13 secs when the drums & bass (very low bass which is also a good tester) kicks in there's some switching of sounds between the left & right channels.

It's a sample from a 21 min track - a very demanding song indeed and one that I use (amongst others) when auditioning HiFi separates.
