It is definitely a good niche. After all movie or online business reviews sites are also like that. They got traffic for some months for some contents and then later will get less traffic. So, it is completely normal. However, in these kinds of niche, you should keep on writing new contents as many as possible day by day. Actually, every niche is profitable if you have lots of ideas on that niche. Let me explain to you more.

Niche means the subject of your interest, in which you have some knowledge so that you can write several contents related to that niche. Actually, every niche is profitable, what matters is a number of contents you can write in that niche. So, instead of thinking which niche is profitable, think in which niche you can write many contents by targeting several different keywords, because more contents you can write, you gonna have more traffic to your website and then more conversions, sales or even a profit without selling anything or recruiting anyone, just from advertisements within your website by applying with services like Google Adsense.

It a very viable evergreen niche. Sure, it might be one that needs constant attention, but as a viable niche yep!! sounds good.

BTW Musical instrument is a pretty awesome niche!
