Hide content on one page of a Wordpress site before Facebook fan page is liked

Need a short bit of code/correct plugin installing on one page of a wordpress website for an up and coming music artist. We need to hide content (which is a link to a soundcloud download for a song) until the user of the site likes the actual facebook fan page of the artist, rather than the liking the website page which is happening now. This is a super quick job for someone who knows coding hence the very small fee. Ideally would like this completed in the next couple of hours.
