The app's icon is orange and has two barred eighth notes. Usually it is at the bottom of the screen in the area that doesn't scroll when you go from page to page. The text at the bottom of the app icon says Music on mine. I think it used to say iPod an iOS version back , or so.
If you still can't find it, go to the search page, by swiping toward the right, and enter a song title or band name and searching. It should show in the list if it made it onto the iPad.
