Bnei Heichala- the Chabad one- esp sung by Benny Friedman. Sang it a lot in Israel, and every time I hear or sing it now, I’m transported back to a narrow, cobbled alleyway from a different world…
Yedid Nefesh- there’s two I have in mind, don’t know who composed them. Also learned both of them in Israel- never even knew of Yedid Nefesh before… the first time I heard it, i had chills running up and down my body… still do every time i hear it.
Mah Tagidu- every time I think of the meaning of the words, I cry… which is awkward at random shabbos tables and simchos. 😉
Don’t Hide from Me- Avraham Fried, and many other Avraham Fried songs I can’t recall now.
Lecha Dodi- I think it’s the Breslov one- Simply Tsfat sings it.
Kad Yasvun Yisroel- the really old one (that is also sung in Yiddish) and Benny Friedman.
Kidshu Brich Hi (Hu)- Chabad song sung on A Forshpiel in Viznitz…
