Hi Tony,
Yes, so much if today’s audio is unintelligible to those of us brought up in a world without computers ( I am a mere child of 70).
ABC Lounge Radio is included in the listings on Mosaic. You can use the “search” icon at the bottom right of the screen. I just entered “ABC” and scrolled down through the menu where, of course you will find all of the ABC Australia national broadcaster stations, then there follows ABC genre stations of which Lounge Music is the sixth down.
Best Wishes
Pete
