MP3jam is a free music finder, downloader and player for Windows. Instead of torrents or P2P networks, it searches for music in public repositories, mainly YouTube, and saves the audio of the found tracks as MP3 files. According to the developer, a meta-search algorithm organizes the scattered YouTube uploads into artists and albums, so you can type the name of a song, artist or album, or paste a YouTube URL, and get a clean list of results. From that list you can preview a track in the built-in player, download a single song or grab the complete album with one click. MP3jam looks for the highest bitrate available (up to 320 kbps) and fills in the MP3 tags using the open Last.fm API, and the saved files can be copied to a phone, an iPod or any MP3 player. The home screen lets you discover new artists by genre, such as classical, electronic, hip hop, indie, jazz, metal, pop, r&b and rock, and by mood. The History tab lists the downloaded tracks and plays them again. In Settings you choose the download folder, turn music sources on or off, pick a color theme and change the interface language. The free version limits how many tracks can be downloaded at a time, and an Upgrade button offers a paid version.
