I want to use a song as my alarm sound, but I want it to be a complete song, not just 30-40 seconds. The first solution that I tried was buying a 3rd party app, which lets you use songs from the iPod Library. But, they are just not as convenient as the built-in alarm clock of the iPhone, because if you forget to open the app before going to sleep it wont play the song. Besides, they also consume a lot of battery. Any other way to achieve this? Thanks.
