I was trying to find a place to comment on this and IMDB seemed the right place. The atmospheric tracks they chose for this series are just fine. However, whoever they hired and made the pop music choices for the soundtrack should've been fired. It's incredibly jarring to be experiencing a foreign piece set in a specific time period (1960s) to be shocked into hearing overbearing music from the 2010s. The 21st century pop is wildly out of place and a stain on the filmmaking - which I must compliment as having very visually pleasing color palette, nice camera work, excellent acting, and perfect set design. But someone has to grab this series back and re-edit the soundtrack choices. Even if 1960s American pop took its place that would at least be acceptable, but I can think of plenty of other Italian hits from the same era that would've worked, too.
