This plugin renders an audio player and playlist for all audio elements within a page. It pulls together audio files listed in posts (typically in the excerpts in posts) and provide a single player to control them. It also keeps track of the play point and can even continue to play the audio on subsequent pages that it is listed on.

Media Downloader plugin lists MP3 files from a folder through the [mediadownloader] shortcode. It reads MP3 information directly from the files. It also can try to get rid of stupid content blockers (mainly corporatives), changing all links to .MP3 files into some download URL without the string “MP3”.
