I am worn in red where a bride should wear white. I bloom for the living, yet cling to the dead. In the Lowlands Away, I rest on her breast the only color left when the song tells her fate. Love placed me there; loss made me stay. What am I?

You thought it was songs, But the app said no? 'Radio Art' ? It's what helps the heat flow...

They used to think I'm underground, In company of all the dead. Yet now all know I can be found Lightyears away above your head. And if you want me in your house? Just go put on some Mickey Mouse!

Trace a circle, gave you the NEWS. These days, one's digital, the other's askew. But both are the same, they obviously share a name.

Lips can be this with and without an additional P. What color am I?
