Certainly, turning your Oxwall site into a music hub with the features you require is an exciting venture! To achieve your goals, consider the following steps:

Customization of Features: As you've mentioned, Oxwall has the features you need, but customization might be necessary. Renaming "videos" to "music" is a viable option, and you can explore additional Oxwall plugins or develop custom ones to enhance the music-specific functionalities.

Integration with Music Platforms: Consider integrating your site with popular music platforms that offer APIs. This way, you can pull in music content seamlessly. For example, you can integrate with music streaming services or utilize APIs to display artist information, album covers, and more.

Independent Radio Stations: Look into third-party services that provide embeddable players for independent radio stations. You can integrate these players into your site, offering a diverse range of music content.

Live Streaming: Explore options for integrating live streaming features. Depending on your requirements, you might need a combination of video streaming services and custom development to facilitate live music events legally.
