Specify the episode and season of the show in which the song appeared. If you're an avid fan of the show, you likely will have caught the episode title or know how many weeks into the season the show is. If you just happen to be tuning in, you'll have to pick-up a newspaper guide or search online to determine the season and episode of the show you are looking for.
Write down or remember specifics about what is taking place while the song is playing. Networks list songs in connection with the action that was taking place while the song was playing. Pay attention to which characters are on screen and to what they are doing. The more details you remember, the easier it will be for you to locate your song.
Check what network the show is being aired on. The best source for tracking down a song is the network website. Independent and fan-based websites might be helpful if you're not sure what network is connected with the show. There are also websites that will help you find songs from commercials, which often air on more than one network.
Use your computer or mobile phone to get online and search for the network website. If you don't know what network the show is on, perform a search for the name of the television show. Alternatively, you can search for "television show songs".
Look for a music heading on the homepage. The network sites all have a menu selection for music, which will take you to a listing of all their shows by episode. Find your show; find the episode; and locate the part of the show you want. If you're using a network site, they will even have a direct link for you to purchase the song if you want to. For example, at the ABC home page it will take you just one more click to reach their music lounge page, with all the information you will need.
