I'm probably a bit late to the party in realizing this, but I guess Youtube videos could be considered an actual format in the same way as vinyl or CD, if only because they at times provide access to music that is unavailable in other contexts.
Below is a video for Madonna's performance of her song "Bad Girl" on Saturday Night Live. According to Wikipedia, it is the only time she has performed the song outside of the confines of the studio. The song itself is excellent. Lyrically, it is a rumination on a person's inability to stop the self-destructive behavior that prevents them from claiming the life they truly want. The line "I'm not happy when I act this way" could speak both to the character's disappointment in herself and also an acknowledgment that her behavior is due to a depression she can't master. I don't know what to say about the music other than that I find the instrumental break towards the middle wondrously emotive, the simple three note pattern played by synthesized strings especially so.
Although David Fincher's video for the song, which depicts a dreamlike vision of Manhattan of melancholy light, chrome, wood and smoke, every surface and illumination seemingly pregnant with poetry, a place that does exist but only rarely, is superb, I tend to turn to the SNL performance instead.
I want from live music something I can't get from the studio version of the same song, and this desire has rarely been met in all of the shows I have gone to. But there is something decidedly real about the performance below. It starts, I think, at a slower tempo than the studio version of the song, and with a bit of hesitation. Gradually, imperceptibly, it begins to cohere, and, as the confidence Madonna's singing increases, the band, especially the amazing team of Victor Bailey on bass and Omar Hakim on drums, begins to push, like a great jazz rhythm section, Madonna to even further levels of intensity. By the time Hakim plays that last huge fill around his kit culminating in the forceful strike of the crash cymbal on his left by the stick in his right hand just as the lights illuminating the band go down again, you can tell by the expression on his face that we have reached the emotional plateau, one higher than that of the studio recording, that nobody was quite sure would be arrived at as the song began.
