0361-0370, 0371-0380, 0381-0390, 0391-0400, 0000-0400 & 0301-0400 will become available as soon as the relevant packs are online.It's also a good way to divide the smaller.
i can make 50-packs if you want as well. even a monthly 0000-0xxx is thinkable but i don't know if the interest is high enough for those who want to download/upload. please leave me a PN if you are interested!
However, Most people who download the old songs seem to be all at once.
