In reply to B_Roni.

I kinda agree but the thing with Travis is that he sounds too much like Justin Timberlake (although Travis is a better singer)

With Zayn, i think the sale issues are due to the fact his fan base was so young and the music was a big jump in mature lyric and sound, if he had gone a more friendly poppy sound like Justin or Justin he may have faired much better but instead he went for a more Miguel & Weekend that means he has ti build a new fanbase.
I respect him for staying true to himself music wise and hope that the second album is as good as the first
