I've listened to tracker music since the 80's and I still do it basically every day. Whenever I have a bad day or feel the lack of motivation; tracker music always helps. And to be honest, it's probably what's getting me through my 20 year long depression.
There are so many good tracker songs I could recommend, but I'll instead list a couple of my favourite artists: Elwood, Radix/Rymdlego/Mosaik, Fearofdark, Necros, Purple Motion, Lizardking, Malmen, Beek, Dubmood, Skaven, Virt and so many many more!
