Another popular program that is capable of this is called Audacity. You will only need to download this software if you do not have a Realtek sound chip installed.

This means that any outside noises that are made while you are recording will be added to the track. If your phone were to ring while you were recording the track, your ringtone would be added into the song.
Not only will you get the outside noises on your track, but your recorded YouTube Music will not sound right and be of very poor quality.
To correct this, you can use a Line-out to Line-in method. All you need to do is select 'Line in' as the input method and run a cable from your 'Audio-out' to your 'Audio-in'. These cables are generally standard earphone plugs for both in and out, so this is all you will need. You can pick these up for a few dollars at an electrical store. Because the 'Audio-out' or headphones plug is being directed straight back into your 'Audio-in' microphone socket, you should be able to eliminate all background noise and get a good quality sound recording. Should your phone ring while you are recording, you should be able to answer and have a chat without restarting your recording.
