Snoog Dogg & Dr. Dre - Nuthin' But a G-thang (acapella) C# major
Ed Sheeran - Happier (acoustic guitar) C major original
UPDATE - this one has an intro - thanks for previous likes, downloads and plays.
Ed Sheeran speeded and pitched up to C# major with Audicity (DAW). @0:10,5 edit on guitarstrum.
Some extra stereo on mental. Send reverb on vocal.
Cut out high pitched vocal [3:21 - 3:31] and filled space with a Sony Simple Delay on the 'chill till the next episode', but used the acapella outro.
