Currently, my audio-only collection (I call it “R.E.M. Box”) sits at 100Gb of official audio (R.E.M.‘s and band members’ isolated) and not many live shows separated by year and album. It’s perfectly organized now, after a few years of tending to.
The R.E.M. gigs folder, which I haven’t listened to yet, in order to maybe incorporate in the R.E.M. Box or delete or else, is 53Gb on my HD.
And the video folder in my external drive is around 300-350Gb so far with almost everything the band has ever released, except for the stuff I have on DVD (Tourfilm, Road Movie, Best of, Perfect Square). I think all the smaller video compilations are there, along with many live shows, the BBC box, the REMTV box, the Blu-rays, the extras and so much else.
