Well, as I said no one is making you listen to the parts of the song, I've only heard the merged files once-twice and they are barely listenable due to poor quality (not complaining
), so I won't get tired of the song before it's out as I barely heard how it sounds. I think that AVEX is trying a different promotion approach that can't hurt the single but MIGHT create more HYPE and boost the first day/week sales. And even if by ANY chance some people get tired of listening to ringtones lol there is always Days to look forward to.
