Recently, Martin has transferred recordings from 108 DATs to hard disk. Unfortunately, he didn't preserve the ids on the DATs, but instead segmented the audio according to tracks according to silence. This is not the same, since ids are sometimes one and sometimes two tracks on these dats. Thing is, the recordings were originally stored on 78s. The ids consistently describe these records, i.e. for each record has one id, no matter how many sides it has.
