Still in an Adult Swim mood, was watching the original promos tonight and getting super nostalgic. The music in these ads was always prominent to me as a kid. After all these years I’ve finally looked into what it was. The track is Mambo Gallego (D Code Mix), which is a mix of the original by Tito Puente. Very sweet tune, happy to finally know what it is now. I made the video above which is the full song over the compilation of original promos/bumps. The track can be downloaded here.
