So in school we try to listen to music whenever possible, but the damn teachers wont let us. So we put in one earbud so we can somewhat satisfy ourselves. On some days, the battery is low when we try to listen. My idea is an update/app that allows when you listen to your music to have only one earbud playing so you save battery life, and make you listening seem less noticeable since 1 earbud blasting is quieter than 2 blasting.

Just something I thought about. It would be available on smartphones (blackberry, android, iPhone) and iPod touch. No need to have it for iPad, why the fuck would you bring an iPad to school.
