Currently, my music library consists of files in various states of compression - MP3s, FLACs, and WAVs. I wanted to sync these files to my phone, converting only the WAV files to FLACs, both to save on space and because my phone has problems recognizing them. To do this, I set my phone up as a sync device, and in the on-the-fly conversion settings, chose "convert to FLAC" and "only convert lossless files". When I do this, however, MB syncs all files without conversion, treating the uncompressed WAVs the same as the lossless FLACs and the compressed MP3s. Is this a bug anyone else has experienced, or does anyone know of a workaround?
