I'm prepping my music library in anticipation of a December delivery of my Model S... In the past, I've always placed an iPod Classic in the glove box of my car, hooked it up and not thought twice about it. Given that Tesla currently only supports direct connection of USB thumb drives (and I've heard that the FLAC files sound great compared to a lossy format like MP3 or AAC), I'm re-ripping my CD collection. My plan is to mix and max FLAC with MP3 and AAC on a thumb drive. I'll use "A Better Finder Renamer" to randomize my favorite 5 star songs... But to do so, I'll need to remove the file extensions from song files. Arcane question but... Will the Model S play back a music file without a file extension as long as it's a valid music file? I'm trying to combine two different libraries (compressed and uncompressed) into one playlist and I don't want duplicate files. If I remove the extensions and then copy to the folder the higher quality files they will replace the compressed files. Unfortunately, for many songs I purchased them online vs. a CD. But I'd still like to have them in the playlist... Thoughts?
