I want a quick way to be able to select a bunch of MP3s and burn them to CD (as MP3s on a data disk) for playback in the car, or to a usb key. Lots of apps including iTunes & Windows Media Player do this. However, a lot of my MP3s are at 320kbps, and I would rather transcode them down to 128kbps so I can fit more songs on a disk / usb stick, and the speakers in my car are rubbish quality anyway.
Is there an application somewhere that does this in one easy step? Windows Media Player will only let me choose a maximum bitrate if I burn the files as wma, and iTunes doesn't change bitrate at all.
