Would 你 consider bands like Lacuna Coil, Evanescence, 或者 Apocalyptica "Symphonic Metal"?

Ehh...Apocolyptica I would, the other two not so much. They are 更多 Gothic, which is generally about atmospheric keyboards than symphonics.

Good question.    Depending on the song. Most of their songs are orchestra metal.

Apocalytica could be classified as symphonic metal because of their 音乐 style. Lacuna Coil wouldn't count as symphonic metal. They're classified at 哥特式 metal. 伊凡塞斯 does have some elements of 哥特式 metal, but it's actually considered alternative rock.

No. The closest one would probably be Apocalyptica. I 爱情 Lacuna Coil, and 伊凡塞斯 is my 最喜爱的 band, but I can't call them "symphonic metal". I would really just categorize them as "modern rock" 或者 "normal rock". They both right great lyrics like a symphonic metal band, though.

Lacuna Coil and Apocalyptica yes. I 爱情 伊凡塞斯 but I think it's 更多 rock 或者 哥特式 metal.

Maybe apocalyptica but not the others.

I don't consider either Lacuna Coil 或者 伊凡塞斯 to be Symphonic Metal. 伊凡塞斯 seems 更多 Modern Alternative Rock while Lacuna Coil seems to have 更多 of a hard rock/metal (alternative) edge to their music. Apocalyptica seems 更多 geared toward symphonic metal. though they maybe 更多 avant garde type of band since they use cellos.
