Since they've redesigned the Chromecast promotion web site is there any easy way of finding content sources that work with desktop web? It all seems to be very phone app oriented.

What's slightly annoying is that sites like Tunein Radio get promoted because their Android App supports Cast, but their website player doesn't (yet).

I guess iPhone users are probably in a similar situation as there's bound to be sources with a Cast ready Android app but where the iOs version doesn't do Cast yet.
