yeah, idols are notorious for lip-synching. but i've come to terms with it. i know the boys are very busy and sometimes they just can't focus on just music or vocal training (with dramas, photo shoots, & everything in between!). it's very understandable, at least that's what i think.
..ah. i haven't seen a NEWS con, so i can't comment whether they lip-synch the whole thing or most of it. but, i've read a concert report and the girl was saying she really loved the concert, but it was along the lines of 70-80% of it being lip-synched or something. watching TOKIO, KAT-TUN, & KANJANI8's concerts, i would say most of it was actually
live, esp. TOKIO & K8. but then again, they're the most music oriented groups in JE.
