BS”D
Years ago I bought a cassette of Sefardi piyutim produced by one of the Syrian kehillos in Brooklyn, and there was a warning referring to the posuk in which hasagas gvul is mentioned (from last week’s parsha). I’ve also seen “issur hasagas gvul” on some “haimish” albums.
In any case, trying to find a heter for copying in most cases smacks of the “naval birshus haTorah”. Listen to online radio or use the listening stations in the sforim stores, keep track of what you like, and buy only what you like.
