OpenKJ vs TKaraoke

OpenKJ is open-source karaoke hosting software for karaoke DJs, built and tested for Linux, macOS, and Windows. It integrates with OpenKJ Songbook, which supports web-based song search and submissions. Singers can use Songbook apps for iOS and Android to browse or search a songbook, submit songs with requested key changes, and save favorites. The web submission site can also serve as a venue kiosk, and sign-up requests are sent directly to the host computer. Songbook can optionally display download-vendor catalogs; the project says these are updated daily. OpenKJ SongShop supports purchasing and downloading karaoke files on the fly, with PartyTyme listed as the only available vendor. OpenKJ Tools provides utilities for ReplayGain adjustment, archive handling, zip compatibility, and filename capitalization. Those tools are marked experimental, and the project recommends backing up the library before using them. OpenKJ is free; Songbook starts at $9.99 per month and has a one-month free trial.

TKaraoke is a karaoke player that indexes thousands of songs and lets users search by song name, singer, songwriter, or lyric text. It can play YouTube content as if it were on a local hard drive. The Songbook controller app lets phones, tablets, or laptops control TKaraoke editions; Songbook 2 is available free from the Apple App Store and Google Play Store. On Android TV, TKaraokeUSB plays songs from an external USB drive without a song server on a computer. It supports 4K songs on capable devices, voice search in English or Vietnamese, and formats including MKV, MP4, VOB, AVI, M4V, and MPG. The TKaraokeUSB free version is limited to 1000 songs. TKaraokePro2 runs only on 64-bit computers running Windows 7 or newer. Its demo key costs $1, paid once and stops songs after two minutes; the full key costs $100, paid once and unlocks Pro features, with free lifetime upgrades stated. The product is listed for Android, iOS, and Windows.
