I'll have to check and see what's possible. That Machine Head album is available, but I haven't seen any more In Flames or Parkway Dive instrumentals turn up. They'll have to be DIY, which will take some extra time to see what works and if any tracks do, also making them. But I've made notes to check em out. :)
I had been putting it off because the only copy I could find is the 128kbps version... but that may be how it was printed on the promo. So I may just go with it. Gotta make the time.
