The answer is in the moving, not what you are moving. I suggest quit moving, because a few extra boxes is not a big deal. Getting rid of collected media is. I've never met a person who didn't regret dumping what he/she could have kept for the sake of 1/2 a PU load of boxes. I'm sure someone will chime in that it was the best idea they ever had, BUT no one I personally know.
I understand being shuffled off to the old folks' home and physically not having the resources, space, or money. I also appreciate selling a collection for a decent price, but making a choice between spending an extra hour moving a complete collection in most cases vs streaming or archiving is an easy choice for me.
I also keep reading how people moved their collection to CDR, HD, or Servers and SELL or even give away the collection. Completely unethical and illegal, UNLESS you keep the originals. Why do you think they are called "RIPS"? Because they ARE ripped-off and ONE person has paid for the use rights, NOT TWO.
In that case, paying for a service is at least putting a few coins in the song's owner's pocket. Everything I have, songs or movies I have the original back to VHF, CD, DVD RtR, Records or Cassette. I have a few that were remastered from RtR or LP, and a few by different record companies, BUT I still keep the originals.
I use the Music Channel or a Server, if there is a gathering, but for a good concert or listening session, I fire up the record players, RtR, CD players, and even a good cassette player for a few of the old garage band recordings I have. Some things are truly one of a kind and exist only one way.
