When u can't seem to download the main song for the wedding 😳🥺😭⚰🪦

I ran into an issue. Could not download/ purchase main song for a wedding. They sent link from YouTube. I could have easily played off of YouTube but I have been in situations where wifi is not available, and cellphone/Hotspot service is pretty much 💩. So I was fortunate enough to simply record the song on another laptop with some recording software. I know there are some sites where you can download to mp3 but a lot have been removed or have crazy viruses when downloading.
