DJs often say: edit the short message "9002+ click the song if you want" and send it to10668001751. The cost is one yuan, excluding the communication fee. I see.
I ordered it once, waited for half an hour, then turned it off and then turned it on again. Actually, it's playing this song, but unfortunately it can only be heard at the end.
In addition, you can order songs at www.musicradio.cc in official website.
I hope it helps you.
