Snoog Dogg & Dr. Dre - Nuthin' But a G-thang (acapella) C# major
Ed Sheeran - Happier (acoustic guitar) C major
This is the first version with NO intro,
Ed Sheeran is speeded and pitched up to C# major with Audicity (DAW).
Used first 5 seconds of mental twice, with an repeat edit @0:04,5 of the guitar-strum just before on lower volume. Some extra stereo on the mental. Send reverb on vocal.
Cut out the high pitched vocal [3:21 - 3:31] and filled that space with a Sony Simple Delay on the 'chill till the next episode', but used the acapella outro.
