For a low level program, first make sure it isn't too fast OR too slow. When you listen to it, think about how you would push into elements, or think about "Hey, that music cue would be great for a jump". If you can't imagine doing something when you listen to it, it may not be right for you. Also make sure there is one change of tempo somewhere so that you can highlight footwork, or a spiral, or some sort of element (plus, this keeps interest in the program). Also, think about what your strengths are as a skater. If you are better at jumps, think about music that can highlight those. Or if it's stroking and inbetween elements, there is music that can accomodate that as well.
But yes, you must LOVE your program. If you get sick of it or hate it, it's very hard to keep your energy up and look like you're having a great time.
