Dexter comes home, hears the Make your own kind of music song, then sees the dead kid and dramatic melody starts playing. How is it called?
The track is actually 'Argentina - Daniel Licht' which is Track 10 on Dexter - Season 7 (Music From The Original Series). Listen from around 30-35 seconds in and you'll recognise it within about 10 seconds!
