Why bother sending the standard ecard when you can say it with a song? Postcard.fm is an elegant, idiot-proof service from the same people who created the fantasy label site The Next Big Sound. The service lets you easily combine a photo, a song and a message for an awesome e-greeting. Photos can be directly uploaded from your computer or you can type in an image’s URL. You can also upload your own music file or search for a song using SeeqPod’s library of mp3 songs. Now i can finally mashup those wonderfully snarky greetings from someecards with equally cheeky music.
