How can I listen to my favorite radio station on Amazon Echo?

Stacy's mom likes a radio station in Pittsburgh, but it will only work on radio.com. Is there a way to get it directly on from her Amazon Echo? Leo says that if it's on TuneIn, then you can get it directly. If not, check IHeartRadio. You may be able to set it up using the Echo App, but it's not an easy process.
