I've created a new and better sample, with a higher volume and cutting out some of the peaks and then set the ATTiny85 to play at double the speed it was previously, which was already a factor of 4 faster than the sample code said it should be and...

P.S. I've only been testing this with the vDrive ZX at the moment but does it make difference to the experience! It just feels and sounds right. It's as if you're using a real Microdrive. It make soooo much difference.

I'll generate a schematic and post the code so that others can make this. Maybe Charles can change the vDrive and add this instead of the beeper? The cost of the components is probably in the region of 50p or less.
