The next hip-hop entry to the top 20 songs turning 30 years old countdown is slightly controversial, in that some would argue this track samples too much of a song that hit a previous countdown. I would argue the song has enough originality, thanks to Warren G’s hypnotic vocal, to earn a place in this list. Add to the fact this song gave renewed vigor to Michael McDonald’s track that gets sampled, and you have a strong entry at #16 – It’s Regulate by Warren G featuring Nate Dogg.
