Uploadable sheet music?

I was wondering if someone can provide me with a link (if it exists) for sheet music for songs that can be directly uploaded into Cubase? You know, say you want Cubase to play “Total Eclipse of the Heart” or “Wicked Little Town” from Hedwig and the Angry Inch. Does such a thing exist? I googled “Cubase sheet music” but that just sent me to sites to buy sheet music and I am not sure if that’s just a PDF of the sheet music or if it can be put directly into Cubase and you just put your instrument - say piano - in the right slot and it just plays the song.

Any help would be appreciated.
