Lawrence Power has a new five track NSF available on his page. Full of pure 2a03 goodness, retro but melodic. Debate NSF players of choice endlessly in the comments. 3/5 is perhaps the most adventurous one in the pack, but they are all worth a listen.
nab it!
I like that he also released the .ftm file, so I can study the track in Famitracker. This is also usefull for converting the tune to PAL, so I can play it back at the right tempo in my PAL NES :)
