Pros of Clementine

• More mature and stable project with a larger user base
• Supports a wider range of audio formats and codecs
• Better integration with local music libraries and traditional music player features

Cons of Clementine

• Less focus on social and collaborative features
• More limited support for streaming services compared to Tomahawk
• User interface may feel less modern and streamlined

Code Comparison

Clementine (C++):

void Player::Next()
{
  if (playlist_)
    playlist_->Next();
}

Tomahawk (C++):

void AudioEngine::next()
{
    tDebug( LOGEXTRA ) << Q_FUNC_INFO;
    if ( canGoNext() )
        playItem( nextItem() );
}

Both projects use C++ for their core functionality. Clementine's codebase tends to be more straightforward and focused on traditional music player features, while Tomahawk's code often includes more complex logic for handling various music sources and social features.

Clementine is generally considered more suitable for users who prefer a classic music player experience with strong local library management. Tomahawk, on the other hand, caters to users who value social features and integration with multiple streaming services. The choice between the two depends on individual preferences and use cases.

Pros of MPD

• Lightweight and efficient, designed for server-side operation
• Supports a wide range of audio formats and protocols
• Highly customizable with numerous client applications available

Cons of MPD

• Lacks a built-in graphical user interface
• Limited social features and music discovery options
• Requires more technical knowledge to set up and configure

Code Comparison

MPD (C++):

bool
playlist::AddSongToPlaylist(const char *uri, const char *playlist_name,
                            unsigned *added_id)
{
    return spl_add_uri(uri, playlist_name, added_id);
}

Tomahawk (C++):

void
PlaylistModel::addTracks(const QList<Tomahawk::query_ptr>& queries)
{
    beginInsertRows(QModelIndex(), rowCount(), rowCount() + queries.count() - 1);
    m_queries << queries;
    endInsertRows();
}

MPD focuses on server-side playlist management, while Tomahawk emphasizes client-side playlist handling with a more modern C++ approach. MPD's code is more low-level and C-like, reflecting its focus on efficiency and broad compatibility. Tomahawk's code uses Qt framework and higher-level abstractions, indicating a more user-friendly, desktop-oriented application.

Pros of Mopidy

• Modular architecture allows for easy extension and customization
• Supports a wide range of audio sources and streaming services
• Active development and community support

Cons of Mopidy

• Requires more technical knowledge to set up and configure
• Limited built-in user interface options

Code Comparison

Mopidy (Python):

from mopidy import core

class MyFrontend(pykka.ThreadingActor, core.CoreListener):
    def __init__(self, config, core):
        super().__init__()
        self.core = core

Tomahawk (C++):

#include "tomahawk/source.h"

class MySource : public Tomahawk::Source
{
public:
    MySource( const QString& id, const QString& username );
};

Key Differences

• Mopidy is written in Python, while Tomahawk is primarily C++
• Mopidy focuses on server-side audio playback, while Tomahawk is a full-featured desktop player
• Mopidy has a more active development community and regular updates
• Tomahawk offers a more polished out-of-the-box user experience

Both projects aim to provide a unified music listening experience across multiple sources, but they take different approaches. Mopidy is more flexible and extensible, while Tomahawk offers a more traditional desktop application experience.

Pros of Quodlibet

• More actively maintained with recent updates and contributions
• Extensive plugin system for customization and feature expansion
• Better support for large music libraries and various audio formats

Cons of Quodlibet

• Less visually appealing interface compared to Tomahawk's modern design
• Steeper learning curve due to its extensive features and options
• Lacks some of Tomahawk's social and streaming integration features

Code Comparison

Quodlibet (Python):

def __init__(self, library, player, window):
    super().__init__()
    self.library = library
    self.player = player
    self.window = window
    self._set_up_widgets()

Tomahawk (C++):

TomahawkApp::TomahawkApp( int& argc, char *argv[] )
    : TOMAHAWK_APPLICATION( argc, argv )
{
    setOrganizationName( QLatin1String( TOMAHAWK_ORGANIZATION_NAME ) );
    setOrganizationDomain( QLatin1String( TOMAHAWK_ORGANIZATION_DOMAIN ) );
    setApplicationName( QLatin1String( TOMAHAWK_APPLICATION_NAME ) );
}

The code snippets show different programming languages and initialization approaches. Quodlibet uses Python with a more straightforward class initialization, while Tomahawk employs C++ with a focus on setting up application-wide properties.
