CD is the most important for me, it is the only source I use for serious listening sessions. (No TT before you ask)
I use my DAB tuner and Squeezebox for convenience since I often work from home. The SB can be remotely turned down whihc is dead handy, when phone rings etc.. The Hifi is in another room to my office. Only ever really listen to Virgin radio on the DAB, since they don't play wetlife, mcfly, that dion woman, etc.. Though they are playing the bew Paul McCartney one which is really getting on my tits.........
Radio allows me to hear new music which I like. Speaking of which, Reading festival is on ITV2 tonight if I remember rightly....
