The term "#nowplaying" is the most talked about topic on Twitter on the morning of April 19.
In second place is the phrase "#DontActLike." Microbloggers are using it to talk about the things they hope people do or say around them.
"Don't act like" ... "my best friend when i just heard you bitching about me," "you don't listen to Justin Bieber too ! hahah everyone does that's why he got almost 2MILLION followers!" or "you're a bad man when you still live at your parents' house," say people on Twitter using the "DontActLike" hashtag Monday morning.
The name of teenage heartthrob and singer Justin Bieber has moved up the charts two places into the third position, just ahead of the hashtag "ladiespleaserealize."

Twitter users are talking about disruptions to flights across Europe caused by the volcanic ash as well as making ash and volcano-related jokes.
Korean DJ Taeyeon is reportedly leaving her job as a radio host on MBC Radio "Chin Chin." Fans on Twitter are using the hashtag "TaengDJ" to show their support for the busy DJ, pushing the "#TaengDJ" into sixth place.
