I agree with that when it comes to ALL entries, I don't like to write hate comments, I just write if I love something. I don't like to be rude and disrespectful towards hard work of all those artists, even if the song is really bad. I also don't understand why people are going to videos on Youtube of some song they can't stand just to write rude, mean words. I find it all childish just! Like you DO IT better if you can, instead of doing nothing in your life and just writing awful comments.
Absolutely agree with what you both said. But I think it is okay to express disappointment about a song as long as you explain what makes you not like it. For myself, I can say that I do so in this forum. Even about the song I like least this year (San Marino that is) I can't say I hate it, I just dislike it. Hate is a too strong word and sometimes People want to hurt feelings, but that is something one shouldn't do. Or when you laugh at an entry. It's disrespectful. As you said, the artists work for it and shouldn't be treated in a wrong way. It's better to Support the Songs you love instead of writing hateful Statements about Songs you don't like.
