2PM talks about his unhappiness regarding 2PM’s debut song ’10 points out of 10′ on SBS Strong Heart aired on 8th June.
2PM lead vocal JunSu said on the show, “I have been a trainee for about 4 years after coming up to Seoul from DaeGoo. When I first received the song ’10 points out of 10′, I really liked it. But Park JinYoung only gave me the part which go ‘Yayyy~’. The whole song is about 3 minutes and 22 seconds, and my part was only ‘yayyy~’.” JunSu was unhappy that as the lead vocal, his part to the song was so short.
