Into You making the top 20
I'm In Control is great! I wasn't expecting to see it on any countdowns given its awful chart performance
The Sophie Ellis-Bextor one is quite good and the video is nice too. Love On the Brain and You Don't Know Love are also some of my favorites this year. I especially agree with your Olly comments: this was a nice (if short) return to form for him.
I think the same about Hotter Than Hell as it took quite a while for me to get hooked. It has great replay value as you mentioned. I wish she'd release something with more substance though; her voice is too unique for simple dance-pop.
The Kungs track is another favorite. It didn't do too well where I am but managed to put up some impressive numbers on my chart without the radio exposure.
