R&B singer Trey Songz finally reached his breakthrough in the UK, as “Simply Amazing”, the second single from the album in the country came in at #8 on the UK Singles Chart. Stateside, we were service the T.I.-assisted “2 Reasons”, but Songz has called “Amazing” one of the most important songs of his career, so hopefully we receive the song here as well. Meanwhile, first single “Heart Attack” is making moves on pop radio. Exciting times for Songz! Chapter 5 is in stores this Tuesday.
