Hi, Sara - Yeah, I think my two ways might work pretty well for you. Click here to get to CDNOW, and try searching for a song.
You can get Noteworthy Composer if you Click here. It's a shareware program, which means you have to pay a $40 fee to get all the features of the program. The free trial version will do everything you want, and it's a very easy program to use. You just copy the notes from the magazine onto a score in Noteworthy, and hit "play." Works like a charm, and you can save the tune and play it later.
