Hearing music using the Datassette

I remember, a long time ago I had a program for the Commodore 64 with which I could hear music or any sound recorded in a cassette through the Datassette and the monitor, passing, clearing is, for the c64. It was, I remember, a program that left the screen in white, I imagine in order to give priority to the SID and to the Datassette. The thing worked, clearing is, to a level of very poor sound, but with an important effect: I could hear my favorite music through the Commodore 64.
Does somebody know how to program something like this? Does somebody have this program?
Thank you,

I had created a sample recording utility which uses the datasette.

Very easy really, As far as I remember, a memory location is read while the audio tape is playing. If the signal on the tape is above a specific level (or something like that!) a bit is set on the location. Unfortunately not surprisingly, the recorded sample is 1 bit only! (The major advantage is that you can store 8 samples in 1 byte!

As far as I am aware, I had submitted this program to Binary Zone PD nearly 10 years ago! Contact Kenz for more details. The program was released under the 'Fantasys' label!

Given that the datasette will operate. ie. no other code have put it off. This code will give you sound in your monitor.
