When covers are recorded, I feel that they should offer something new. That's possible, even if the band covering the song and the original artist are from the same genre. Opeth's cover of "Circle of the Tyrants," for example -- they added parts to the song and made it sound more like Opeth. At the same time, the integrity of the song remains.
It can also be interesting for bands to cover songs live on occasion -- I consider it a tribute to the original artist (usually one that inspired the band), and can be nice if performed well.
