Best Music Parts

bmp stands for Best Music Parts. It's a simple CLI tool working along with the Music Player Daemon (MPD).

Purpose

When listening to music, there is sometimes a favourite moment in a song: a chorus, a guitar solo, an amazing variation, whatever. Something you love. A part of a song that you wish you could remember the position of so you could listen to it again at any time.

That's what bmp is all about: marking all the musical moments you like the most and playing them automatically. These time sliders are saved in an easy to edit, easy to share text file.

bmp tries to keep things as simple as possible and provide an enjoyable audio experience. It works on most systems, binaries are provided for Linux, Mac and Windows.

Features

• Interactive shell
• From this shell
  • Mark one or many locations while listening to a song
  • Edit those locations
  • Send the song playlist to MPD and start playing your favorite parts

Installation

Binaries for most amd64 platforms are built for every release. Please just grab a binary version of the latest release.

However, if you have a working Go installation and want to build it, just run

$ go install github.com/matm/bmp/cmd/bmp@latest

Usage

$ bmp -h
Usage of bmp:
  -f string
        bookmarks list file to load
  -host string
        MPD host address
  -port int
        MPD host TCP port (default 6600)

To connect to a MPD server, bmp reads the $MPD_HOST env variable by default. You can also use the -host flag to provide a MPD address, i.e. bmp -host 192.169.1.10. The default port 6600 will be used.

Run bmp to access the interactive shell:

$ bmp
>

or load an existing bookmark file you saved:

$ bmp -f myhits
Loaded 2 songs, 3 bookmarks
>

Tutorial

Let's take a simple example. I just loaded a playlist of Metallica's Black Album) that is ready to play.

From there, I want to

1. Listen to track 5, Wherever I My Roam
2. Mark the range 00:48 to 00:56 because I like this part
3. List to track 8, Nothing Else Matters
4. Mark the range 01:00 to 01:23 then 03:03 to 03:24
5. List the current bookmarked locations for a quick preview before saving the list
6. Save the list
7. Exit and run bmp with -f this time to load the saved bookmarks and start playing

Here we go:
