Sam Smith's song was trash in comparison to Gaga's. Just last year people were saying how mediocre his song was. At least Gaga's song had meaning. The performance was powerful. Any song that brings to light the horror of sexual abuse/rape is going to be "over dramatic."
I'm just a fan of the thought that because a song is about a certain subject it automatically makes it worthy. It reminds me of how Miranda Lambert won all those awards for "Over You" because it was about her (ex) husband's brother dying. The song sucked, though. Who cares what it's about? "Til It Happens To You" isn't a good song. I appreciate it has a good message, but it just isn't a good song.
In the end Gaga's performance felt forced to me and not genuine. That's my opinion. Some of you disagree, which is fine.
