Hello Murre300 and welcome to Chordie. you will find that all the Members of Chordie are kind helpfull people and that Per, the founder of the site, is always willing to listen to helpful suggestions to improve the site. However there are ways of asking and I would suggest that yours is not really the way. Many years ago I learnt that asking politely gets far better results than rudely demanding.
Chordie is a search engine, it hosts no songs apart from the original ones written by Members in the Songwriting section and finds chords, lyrics and tabs from other sites on the Internet. The songs are sorted and indexed and presented cleverly to appear to be hosted here. With the thousands of songs and number of videos available, linking and embedding a video of the song would probably be an extemely difficult, if not impossible task. However if you have the skills to write a programme that would do what you want I suggest that you write privately to Per at admin@chordie with your ideas.
