Handle edge case on songs with hyphens in them

If you look at the catalog.get(undefined) it has several photos in it that reference songs that have hyphens in them.

clean the database?

Cleaning the DB would not scale, but in this app during the given time it is a static list, so that is feasible. I also do not think detecting this would be too complicated: if we split and there's more items we join the first additional items assuming it's just the song/artist name.
