After listening whole album I agree, Appereciate is more than okayish song, not my favourite on this album, but it really got me to goosebumps. I think this is exactly song with Nana's vocals and I hear Anna Nordell in Slowly. Actually I really love 8 from 11 tracks()! Album is sooooooooo great, this one and Sanna's album are kind of masterpieces.
PG, could you please write credits for tracks or just backing vocals if you have this info?
Oh, sure!
