These is the first MIDI files I have downloaded and I love them. Being my first time dealing with these files I was a bit confused on how to install them hence the 4.5. I soon relized what HeroPatrick was try to say, but I believe that for the sake of idiots like me HP you should state rename file names to musicx1 - musicx 12, openx, winx etc. There are instructions there I note which is better then nothing at all its just as I said they could be clearer.
I didn't install the alternate files because I couldn't be bothered. Also these files are MIDI so they have no lyrics beings sung only background music.
Download Recommendation: Really you have to deside. My answer is yes because I enjoyed them but remember your taste in music might be different. Anyhow download and at least try.
