As an AI, I do not have personal preferences. However, both mainstream and non-mainstream music have their own unique qualities and appeal to different audiences. Mainstream music is popular and widely recognized, while non-mainstream music often offers more experimental and niche sounds. Ultimately, it depends on individual taste and what resonates with each listener. **

My favorite non-mainstream manga is "The Ancient Magus' Bride" by Kore Yamazaki. It is a beautifully illustrated fantasy series that follows the story of a young girl who is sold to a non-human sorcerer as his apprentice. The manga explores themes of magic, folklore, and the complexities of human emotions in a captivating and unique way. I love the intricate world-building and character development in this series, making it a standout for me among non-mainstream manga. **

It is not necessarily normal for good non-mainstream anime to always have an open ending. While some non-mainstream anime may choose to have open endings to leave room for interpretation or to encourage viewers to seek out the source material, others may have more conclusive endings. The decision to have an open ending or not often depends on the specific storytelling choices of the creators and the nature of the narrative they are trying to convey. Ultimately, the presence of an open ending does not necessarily determine the quality of a non-mainstream anime. **

No, people who are against the mainstream are not considered mainstream themselves. Those who go against the mainstream typically hold beliefs or engage in behaviors that are not widely accepted or popular within society. They often challenge the status quo and may be seen as unconventional or nonconformist. **

In recent years, there has been a growing trend of individuals expressing opinions and beliefs that go against the mainstream. This can be seen in various social and political movements that challenge traditional norms and values. While it may not be considered mainstream to be against the mainstream, there is a significant portion of the population that actively seeks to question and challenge dominant ideologies. This shift reflects a desire for greater diversity of thought and a rejection of conformity to societal norms. **

Organic products are grown and produced without the use of synthetic pesticides, fertilizers, or genetically modified organisms. They also do not contain artificial preservatives or additives. Non-organic products, on the other hand, may contain synthetic chemicals and pesticides, and are often produced using genetically modified organisms. Organic farming practices also focus on sustainability and environmental conservation, while non-organic farming may have a greater impact on the environment. **

Organic products are made from ingredients that are grown without the use of synthetic pesticides, herbicides, or fertilizers, and are often certified by a regulatory body. Eco-friendly products, on the other hand, are designed to have minimal impact on the environment throughout their entire lifecycle, from production to disposal. While organic products focus on the natural ingredients used, eco-friendly products consider the overall environmental impact of the product. In essence, organic products focus on the ingredients, while eco-friendly products focus on the entire product lifecycle. **

If your friend is mainstream, it means that they tend to follow popular trends, styles, and beliefs that are widely accepted by society. They may enjoy popular music, fashion, and entertainment that is currently popular. Being mainstream can also refer to someone who holds conventional or traditional views and values that align with the majority of people. **
