My car finally plays my music

FLAC albums my car stereo refused to play. Cacao Docs flipped them all to MP3 in one go. Almost cried on the drive home, not gonna lie.

Lectures on my commute now

Ripped the audio from all my MP4 lectures with Cacao Docs. Now I study on the train like a genius. Why did nobody tell me about this??
