You Can Hear it on the AM Radio

My husband found this Select-A-Tenna gadget at the Goodwill (Charity shop for those of you not Americans) and it reminded me of the song by Everclear about listening to the AM radio. I wish I knew how to do that thing where you could just click on Everclear and hear the song because it's a fun one. This gadget says on a tag on the bottom that it will make your weak AM radio signal more clear and loud. What I am wondering is "Does anyone listen to AM radio anymore?"
