Jothar, you’re right about that. However, the post that started this thread didn’t take issue with who composed the melody, but rather, if it were secular music or not. Or at least that’s what we think chesedname meant.
If the gripe is using secular music for a Heimeshe song, then Veroba’s songs would also fall into the same category as Piamenta and Schlock Rock, and OMG, Lipa’s early stuff. Not to mention MBD’s “Yidden”, ‘cept that the latter wouldn’t bother chesedname because it comes from a German rock song, not an English one.
