Re: suitable songs for when bride enters
sweetheart, youtube the name of these songs with the word, “instrumental” attached to them. you will find some versions by stay at home musicians. if you find an acceptable quality, simply download the video through youtubedownloader or real player. convert from flv to mp3 and use. 
you could also use the instrumental of your favourite english romantic song.
I quite like “Dichotomy of Fame” instrumental from Rockstar but don’t know if it’s too loud for you for an entrance.
