Everyone loves to listen to music while working out. And everyone loves to gear there music to the intensity of there workout. We have all seen the treadmills / recumbent bikes with the video screens. Imagine a video screen that displays your workout statistics with an iTunes window floating on top. The machine manufacturer or the gym would pay a fee to Apple to license the entire iTunes library for the machine. Basically, for the period of time that you are working out, you have full access to the iTunes library. In other words, while your working osut you could listen to ANYTHING you want - the new Killers album, the new Beck single -- If you like it you can buy it when you get home.

The key features of the software would be:
1. licensing of the full iTunes library (without ability to download or copy songs.
2. ability to select songs randomly by intensity, physical attributes of the person working out, such as age, athletic condition, etc. (similar to pandora only the software would consider both the characteristics of the band and the characteristics of the listener.
3. the iTunes software would also be matched to the workout program. (i.e. more intense music when going up hills, less intense in the cool down or slow intervals.)

Why would apple or the music companies license the entire library? Because it would dramatically increase sales and promote health. Since you only have access to the full library while you are actually working out, an individual will only have that full access a 20 to 30 mins every couple of days (on average.) In all likelihood they will listen to music they do not own or will listen to new releases. When they are done working out, they will want to take the music with them, realize they can't, and purchase the music when they get home.

I think a real mock run of this could run at a gym on a test basis to see if people will increase their purchasing.

The technology is already their, there is the software the runs on the work out equipment, there are already automatice music selection tools (like pandora or The Filter, and there is iTunes) With some modification, these could all be put together.

Feasibility- all the parts are their. Its just waiting to happen.

Target Market - everyone. The best start might be High School PE classes. Imagine how many overweight kids would jump on a treadmill if it meant they could have full access to the iTunes library while they were working out.

Contracts with every High school, college , and every private gym would be the ultimate goal. Possibly a home model down the road.
