Electro Pop doesn't seem as popular as it was 3 years ago.
The Billboard 100 was dominated by the Lady Gaga, Ke$ha electro pop sound. Most of the songs on the hot 40 basically sounded the same.
Looking at the Hot 100 chart right now. Only one Electro-Pop artist is in the top 10.

It seems like the Electro Pop isn't as popular as it once was. Which is a good thing. I got headaches listening to that music on the radio.
