“Warner Music is Venture Capital for musicians” — Uber’s profit shocker. Ericsson/Nokia 5G awkwardness. Warner Music’s IPO.

Summary: Warner Music filed to IPO because streaming saved the music industry. Uber shares surged 10% before the weekend on word it’s actually planning to become profitable by the end of this year (*depends how you define “profits”). And Europe’s telecom giants Ericsson and Nokia woke up to word the US government may want to acquire them because we’re desperate for a 5G internet network.
