Man what a load of nonsense about nothing. The man is simply asking for test tracks!
Any how it depends what your into but here’s a short list of well recorded music that a good system should be able to make shine regardless of budget.
Cleopatrick, bummer. Lofi rock/metal. Though hard, you should be able to follow the vocals on good system. The opening track is a fair good test.
Leanne la havas. I think it’s self titled. The album with the black and white picture on the front flicker her hair about. Good opener
Mac miler circles. A really good test for vynal replay. There are some very long and low notes in there. If the cart isn’t sorted you’ll know with this track.
Nothing but thieves, broken machine, not made by design. Should put the hairs on the back your neck up.
Fieh cold water burning skin, the whole album is very well recorded.
Robert glasper. Covered opening tracks will give bass reproduction a work out. Lot of quick plucked strings and loads of layers.
Speaking of bass DJ shadows three Ralph will certainly work your system out. I’d be surprised your system can reproduce this faithfully
The prodigy music for the guilted generation, poison, again be surprised if your system can reproduce this faithfully. You also have mindfields by them as well.
Clair maguire, stranger things have happened, opening tracks are very haunting and great vocal test.
Death from above 1979 outrage is now, fast and frantic metal/ electronic muisc system will need a good sense of timing.
The internet, get away. Really airy vocals surrounded by rich and powerful acoustics. You should be able to here all the layers.
This lot won’t be to many’s taste round these parts but good test tracks if you are into this sort of stuff.
Think that will do you for a bit.
