I really like Korpiklaani's first two albums but I would trade their entire discography for one more album like this and Shamániac. Idja is a lot of fun with tons of great melodies, writing, and atmosphere. It somehow still sounds fresh even after over 20 years of all the different variations of folk metal by hundreds of bands. The only downside here is that there isn't a lot of vocal variety so you better like yoiking.
