Firstly, because I like rock music plain and simple and Three Days Grace makes really good music. Secondly, because unlike some bands, these songs don't all sound the same. I can easily tell them apart, but they still have that Three Days Grace vibe, and they're still good! Finally, the music isn't meaningless like some is. They are writing music that is highly influenced by life experiences, especially the One X album. It's great music and I love this band!
