Not only is U2's "With or Without You" one of the most celebrated and covered songs of the 1980s, but its chord progression makes it a popular candidate for mashups. Here, I've paired it with the backbeat from R&B singing group SWV's 1992 hit "Right Here". By which I mean the lesser-known original version without the Michael Jackson sample.

Can you identify the song that the "Worldbuilder Soundmark" sings at the beginning of this mashup?
