This list assumes, of course, that you already have a computer. You don't need the fastest computer to record and mix music, but it should be reasonably fast. Anything with a Core i- or even Core 2-series processor should do the trick. Just don't use a netbook.
Ashford & Simpson also had success writing for themselves: Perhaps the best-known song they sang was the 1980s hit Solid As A Rock.. His music is unmatched in terms of great songwriting, Verdine White of Earth, Wind and Fire said after learning of his friend's death.
This clip is from SOLID GOLD, second season (1981-1982) with Andy Gibb and Marilyn McCoo. Marilyn performs the number 5 song of the week -- the Old Songs -- by Barry Manilow, released in 1981. Big thanks to YouTube'r Cutter Covina for sending me this high quality clip. Hope my fellow McCoo-fans enjoy...! Music arranged and produced by Solid Gold's musical director, Michael Miller.
