This sugary track by August's Imaginarium is both dulce (spanish for sweet) and dulcet (something that is pleasing to the ears). It has an unobtrusive sweetness that still makes you smile but doesn't cause that achy salivary pain on the side of your cheeks.
I've had this little jingle in my head for a couple of days now; it's quite catchy.
