Licensing a Popular Song for Use In a Video

A client recently asked me to licence a reasonably popular song for a promo video of his. I instantly agreed, as I always do when clients ask me to do things I have no idea how to do, and set out to find out how to licence said song. In my google-ing, I came across this article which talks about licensing music for an indie game, but should apply to videos as well: How to License a song for a game trailer

I didn’t really stop to think that the artist may not want me to use their song to advertise something, and that if they did, the cost might be in the thousands of dollars… worth thinking about.

Alternatives listed in this article include making a sound-alike version of the song yourself, which might be the route I choose.
