Kindla 0T, but here goes...

Hey! Heres what i have done so far: I ask the user for his style of music by displaying for example 3 links in the <div id="music"> like rock, pop,sentimental when the user clicks on any of those links i do a quick trip to the DB via ajax and update the div with all the artists that his choice merits... same thing when he clicks the bands name... this time i display all of their songs... and here's where i am stumped... when he clicks any of those songs... it should start playing in the background WITHOUT reloading the whole page... is this possible or am i just barking up the wrong tree? music files are midi, wav and mp3... would be happy if i can have just one if i cant have all three.. Thanks in advance! R
