Walkzarx is a composer, music producer, and remixer best known for his remix of Vicetone's "Waiting" as well as his original tracks "Memories", "Still In Love", "Close To You", "Love Me" and several others. He occasionally produces remixes and mashups of prominent artists' songs such as Illenium, Eminem, Alan Walker, and many more, which he began doing at the age of 15 that eventually led to him producing his own original songs.
The whole part of the mashup video that had Eminem showing up is from the actual song, River by Eminem ft. Ed Sheeran. If you liked this, you should try watching the River video. I got one of my friends into that song. Gives me the chills every time I listen to it. I hope this link works for you guys. It's the River music video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wfWIs2gFTAM.htmlsi=P-Hya6wWl7Bbrnb2
