Audio in background during level load

Hi - I’m looking for a solution to get audio to play continuously in the background during a level load (traditional open command/function) specifically music. I’m looking to revamp my music manager class for my game and I’m wondering if there is a simple solution to do this (eg, running the manager as a singleton when game is booted up, perhaps on a separate thread?). I do not want to use the streaming level feature as it doesn’t provide everything I need, and would require more work to be properly functional.

What should I be trying to do here exactly?
