Talking nonesense Howard.
I can listen to music in my smart roadster at over 70 with the roof off.
Careful placement of quality speakers and sitting position setup equalisation via mic plugged into quality head unit and it's more than doable.
Using the GALA pulse the Volume is speed controlled.
Sitting in mine when parked up it sounds very reasonable, when you exit the car and the focused sound field the music emanating from the car is minimal.
The source is very important MP3 is a very poor choice to listen to if deciding on diskless digital format then use a lossless format.
