Somewhere many pages ago that I can't seem to find there was a mention of composers that have just one hit song and that's it.
I was wondering who could be put on that list
YouTube has someone listed for מה אשיב (you know the song some love and some hate every chol hamoed) I think it's avinoam wolfson - never heard of him.
Tov lehods was composed by Yo Aisentark who has written other songs too but none nearly as popular.
I guess כי הרבית could go on the list too.
Anything else come to mind?
