Why can your CD player not do that for you?
I think if you explore some, you will find that most half decent CD players have enough chipshit inside them to "save a beginning and and end" of a track in memory and replay just that section you have chosen, nearly indefinitely.
Look at your remote. You probably have a "repeat A>B function" or something like that and another control that allows you to set "A" and then set "B" at any place in a track that you want and replay just the section of the track you have set, almost forever.
Sometimes the repeat function is combined into one single button, however. You must then choose whether you want to repeat a full track and entire CD or just on part. Continuing to press the repeat button may open up a new world for you.
