I have a file joiner program that was not expressly made for joining mp3s, and I think it is causing some corruption of the files, since lately mp3s that are joined with this program aren't readable (or visible) on burnt dvds or cds, but the non-joined ones are. I know there are plenty of mpeg/mp3 joiners that have drag-drop lists where you join the files that way, but the advantage of the program I've been using is that it is in my right-click context menu in explorer, so I just select the files and it joins them in alpha/numeric order. Does anyone know of another program like this that is made for joining mp3s and includes convenient right-click context menu usage?
