B1A4 Just Can't Let It Go In Their "Lonely" Comeback

I was waiting for the day that B1A4 went back to more melancholic tunes like "Tried To Walk". I mean, their cute aegyo songs are nice too, but the group really know how to capture deeper emotions with their songs when they are allowed to. That's why "Lonely" may arguably be the best song.
When you first hear it, you initially want to write it off as cheesy and cliche, but as it goes on, you start getting more into it and feel the pain that the boys are lamenting about. The song is about a significant other who left and the can't function without them and refuse to move on (as you can see in the M/V): the typical can't eat and watch movies, looking at past mementos,etc.  Whoever is doing the chorus (I'm only familiar with Baro sorry :/) sounds a bit like G-Dragon. The constant "lonelys" scattered through the song does get a bit annoying afterwards, but it doesn't take away from the song too much. Also, the video on the boys' page doesn't work for international fans, but I was able to get a working link, so enjoy!
