Because the radio station I listen to 6Music is my tool for both discovery of new music and a reminder of music I've forgotten
If you constantly listen to your own tunes, you never discover new ones
There are certain shows on 6 (Lamaq, Riley, Gid Coe, Cerys, Iggy and The Freak Zone) that I listen to all the time for this purpose when I'm in the car, in the bath or the kitchen. Friday and Saturday nights I listen to my own music because I don't really like those even shows but untimately I listen to 6 a lot
