We deliver untouched wav files as received from artists, but we serve level-matched MP3s for streaming and placement because our primary customers are agencies, supervisors, and editors who need to try various pieces beneath their existing picture and voice-over to see what works. If every song is at a different level (depending on the mastering it was given), music buyers are very unhappy. Level matched cues make MUSICLi a better vendor for music buyers to use for their work, which makes them more likely to find and buy music here. In other words: tracks artists paid to make as loud as possible, to "jump off the playlist" and make you jump out of your chair over loudness, will no longer do that in previews and on MUSICLi playlists. By design.
