I never liked Boybands, till recently when One Direction drew my attention.
Even though some may say they are "overrated" and whatsoever, I really do like 1D and I can even say that they are probably my favourite boyband. Before 1D, I knew about Maroon 5 - but... I wasn't that interested in them until a few months ago.
Now, I do really like boybands and their synergy (if that's what its called) really distinguishes themselves from other artists.
1D is now my 3rd most-played artist on last.fm, after my two favourite artists of all-time (Mariah Carey and Beyoncé). Maroon 5 has been my jam ever since, and is my 14th played artist on last.fm. "Payphone" is one of my favourite songs thus far this year, and is probably one of my favourite songs ever by a boyband. "Payphone" also made me re-discover their old songs, and I realized how amazing they were ("Never Gonna Leave This Bed", "Won't Go Home Without You", "If I Never See Your Face Again", "Makes Me Wonder").
Coldplay is decent, but I haven't really been able to get into them bar a few songs ("Fix You", "Yellow", "Paradise").
