Good idea. How would you choose to split the on-card library? Alphabetically? By Genre?
Oh My PalJoey - I have been 'stressing' over this modern problem for weeks now.
This could be the last digital music library I ever build.
The master. I knew CD was locked into those stupid discs and MP3 was temporary. This one feels permanent.
I demand a lot from my music library -- I am a DJ (clubs and radio). I do production. I write my own music and produce other acts. I own well over 1k CD's and like most of them. I listen to lots of genres and lots of eras, literally back to the beginning of recorded music. I will continue to build out my collection with 24bit files. I want it all to be nearly invisible and easy to use, since I don't like to be music snobby
I also have about 2k vinyl records that don't apply here, they will never be digital. If Rip 2.0 goes well maybe I'll combine the vinyl database with the digital database and have my actual master list, but save that for version 2.5.
SO - to your question -- by Genre is definitely out. I don't really do genre's, especially not like most people.
Alphabetically is the most obvious, just leave space on each card for growth, and you can always reshuffle and put new labels on the little card.
Friends have suggested some other interesting concepts: by year, by album name, by playlist, by mood. Each opens up possibilities and has pros and cons.
I'm leaning towards a weird one -- I call it "playlist extended". It requires building a playlist of 40ish songs and then including the entire catalog of the artists in the playlist on that card. Then you continue to make these playlists for new cards with the artists that haven't been used yet. End result is 40 or so artists entire catalog per card.
I am thinking it will force me to group the artists on the card more musically than the other methods. I would just have to remember who's on what card. My JRiver software will keep the 64gb internal on the PP synced with my favorites using playlists and whatnot.
