I've been wanting to do a post like this for ages but I just didn't know where to start. This could be alternatively titled "I can't even tell the difference between these voices anymore" or "if you like ___ you'll like ___"
OK I've started with Imagine Dragons as the base for this post as they're probably the most popular. I'm going mostly by vocals today but in the future it could change. Here we go!
1. American Authors
2. Andrew Belle
3. Mat Kearney
4. Jason Reeves
5. Greg Laswell
Although only one of these suggestions is a band, I promise I covered all moods. You know, as least for me, sometimes I haven't got the energy to listen to Imagine Dragons and all their hype, same with American Authors (I little bit more pop, upbeat, less gritty) so the solo acts provide variety. Andrew Belle has that far away sounding, smooth voice but sings much slower, calmer songs. The last 3 all produce mid-tempo songs for those in-between days when you're feeling calm but you want a little pep. I might put together a little playlist of my favourites from each of these 6 acts mentioned soon, I've already got a work-in-progress version on my iPod. I'm not saying the 6 voices are exactly the same, but they have the same feel (in my opinion, obviously. pretty well everything I post is an opinion).
