Help! wifi music

[sde]

Hey! I am new to broadband and this site. I live way out in the country. I need knowledge on how and what I need to set up streaming and downloading of music etc. I am trying to set up from a At&t uverse wifi router to two older XP laptops to two older speakers. What do I need in the way of hardware & software for a cheap simple way to get Internet music and downloads etc? Please keep your words simple.

Thanks
