The Best 15 of the Past 15 - It was a '90s thing — popping in a cassette and listening to a whole album through until the end. Plus a good concept album had interludes that you would actually sit through and never fast forward for any reason. Don’t forget the legendary "Sexy (Interlude)" on TLC’s CrazySexyCool. The use of the R&B album interlude began to taper off when 2001 rolled in, but that didn’t mean that the past 15 years didn’t have its fair share of memorable interludes. Here are the best of the best. – Jon Reyes (Photos from Top Left: Motown, J Records, Def Jam Recordings, Parkwood Entertainment/Columbia Records, Hidden Beach Recordings, GOOD Music/Sony/Columbia, MCA Records, Arista Records)
