Music may perform better than books and other products, mainly because you can listen to the clips of an entire album in roughly 10 minutes and get a good enough feel for it without buying it to write a short review. If you have another topic that you're passionate about, great, but make sure you have a unique angle on the topic. People can get reviews about a lot of those consumer products anywhere. You need to give them a reason to visit your site.
They are a very clever marketing company, and are everything they say they're not. Beware, and please read. They are smarter than most, which is why they have so many followers. They claim to have the key to training a person on how to successfully create their own lucrative work-from-home blog sites. They do claim to be a lot of work, require a lot of patience, blah blah swoon. You almost had me. 
Basically, anyone who is looking to make money fast should stay away from Wealthy Affiliate. There are plenty of “make money fast” e-books and courses out there, and they are all a scam (trust me). While Wealthy Affiliate is legit, they will absolutely never claim that they teach you how to make money fast. Building a legitimate online business takes time.
No offense, but isn’t making money via Wealthy Affiliate commission through giving them a good review to prompt others to join essentially a pyramid scheme? Seems like you are luring people with the promise of the “easy money” on the internet that is actually a lot harder to obtain, by using earning you made from Wealthy Affiliate by convincing others to join in terms first place.
You could easily do home organizing for people, an industry that has gained a lot of popularity since the debut of Netflix's hit series Tidying Up with Marie Kondo. If you're a tidy and organized person yourself, and you're good at organizing spaces, why not offer your services to people around you? You'd be surprised at how many people, even on your own social media feed, might take you up on doing something like this.
5. Fiverr – Fiverr is a great place to make a few bucks or spend a few bucks if you need some of the services people offer. Basically, everything is $5. You either pay $5 or charge $5. They call them “gigs.” You can offer your services however you choose. If you sell art and you’re fine selling pieces for $5 each, that’s a gig. If you’re a graphic designer and you want to offer your services for $10/hour, simply offer a 30 minute gig. If they need two hours of graphic design, they pay you $20, or $10/hour by buying four gigs.

You also should not join Wealthy Affiliate if you don’t enjoy the community / social aspect of it. A huge part of Wealthy Affiliate is the ability to communicate with other members. It’s a “help and be helped” community. If you have no interest in setting up your profile, asking questions, supporting others, chatting in the live chat sessions, or doing any sort of participation, you will not get the full benefit of the service.
As a current member of WA I can attest to everything that TeamAMR has outlined here.  I was skeptical at first, even when I first signed up, I did not engage but instead I was taking my time poking, sniffing around.  Once I started reading the blogs, the comments I decided to take the plunge and begin the training.  Now I’m a WA junkie, every time I see a member post a success story, I become more committed to my goal and work even harder.  If you are skeptical, it surely is understandable but sign up and snoop around like I first did and don’t be afraid and you will soon see that WA is legitimate and genuine.
