System: Write Songs, Trade for Black Tech, and Build a Business Empire

[System + cutting-edge tech + business warfare + music promotion, with some everyday moments and light comedy. Please don't put this one on your to-read list, or it'll die there.] [The main plot focuses on business strategy and System technology, with music releases as a secondary thread, so there's less of that.] [This isn't an invincible-protagonist story. The protagonist won't start out fully formed: he has plenty of flaws and lacks experience and training, with a clear growth arc.] After suddenly receiving the devastating news that his parents had died, 21-year-old Lin Shen was at a complete loss. But the battery factory his parents had left behind represented their life's work, and Lin Shen couldn't bear to see it go under. He even put his studies on hold to do everything he could to keep the company afloat. Fortunately, a System suddenly activated in Lin Shen's mind, bringing entertainment from 'Earth' with it. By using that entertainment to attract attention, he could earn popularity points and exchange them for cutting-edge technology from the System. He could also exchange points for all kinds of miraculous items. With the System's help, Lin Shen not only saved his parents' company, but turned it into a powerful unicorn that rose rapidly and built a vast business empire.
