Welcome!
- There are multiple ways to do this, but at this point you’re going to get the most options if you just use core.

are you talking about playing the music on the Google home or on your TV with the chrome cast or?

I don’t know of an easy way to do this with Osram Lightify, but maybe somebody else will.
If you have a Hue light strip attached to Hue bridge, there are a lot of apps that can do it, with hue disco for iOS being the most popular.

You can fake it by setting up a harmony activity like “watch creepy movies”, having that turn on a virtual switch, and having the virtual switch start a core piston or other smart app that runs a particular lighting scene. But then the lights aren’t responding to the actual sound from the TV, you were just running a pre-programmed sequence. And for that sequence, again, core is probably the most straightforward choice for use with the Osram.
Other people may have other ideas, though, the community is very creative.
