質問: There are a lot of repetitive songs where I work. How do I mention how repetitive the music is, and convey that I dislike it to an all Japanese staff. Can I use 重ね重ね?
回答: A good word for this concept is ワンパターンな(曲), which is a wasei-eigo term that exactly means "boring and repetitive" or 繰り返しが多くて退屈な(曲). Saying only 繰り返しが多い曲 does not necessarily mean the song is bad. 重ね重ね is a fairly stiff word that is usually used in business settings, and it means a similar troublesome/unfortunate event happening again and again. 重ね重ねの不幸, 重ね重ねのお詫び, 重ね重ねのお願い, etc. 重ね重ねの曲 means nothing to me.
