So, for ten dollars you can get a list of 26 songs used in Oblivion, all composed by the ltanted Jeremy Soule. I thought it was a waste of money but my eagerness cuaght up with eventually and I downloaded the album.
The music is excellent. A lot of the songs are very similar to morrowind;s, in fact it seems music will feel very similar to how it did in Morrowind, if only less repetitive and a bit more suited to where you currently are in the game or what's happening.
Still, after reading a couple interviews I decided a really necessary mod will be something really easy to do, when initiating combat music from exploration or plot music, instead of being abrupt as it was in Morrowind and I hear it is in Oblivion, the current music should fade away into a pause that will last for five seconds, then the battle music would start. The abrupt music changed spoil the immersion.
