Compressing Music Files For Thumb Drive In Car


I just bought a new Jeep Grand Cherokee and the sound system is excellent.......for a car. I have a ton of music in JRiver, and most of them are large files. I'd like to compress them for my 128 gb flash drive. I think I could fit more music on it, and the lowered sound quality for be fine....because it's a car stereo, right?

Can I do this? If so, how?

Thank you all in advance!

Do I need to rip the CDs again through DBpoweramp? I can'f just copy them from my existing library and burn the copy at 320k?
Yes, you can copy from the existing files. Within dBpoweramp there is a Batch Converter. You select the albums you want to convert, select the format you want them in, and select the destination drive and dynamic naming. And that's it.
