Problem is, when you say that your music is from a certain genre, you can give wrong ideas. For example, I write music that can be somewhat labeled as Progressive Rock/Metal, but none of my songs have long solo sections or even long instrumental ones. So, if I tell someone that my genre is "progressive rock/metal", I'll give the listener some wrong ideas or expectations that can ruin the experience a bit.
More on-topic, I agree with snappleman. Just do what you like.
