I love u2's version it's a great song.

My only nit would be that the guitars sound too midi like for my liking, sounds too rubber bandy. you should be able to find a better midi guitar sound than that, that actually sounds like microsofts basic midi font. It takes away from the rest of it in my opinion.

If you have to use a midi part I would use midi piano for the riff.

You probably need a better midi sound module

You could use some harmonies on the "where do you go when you're lonely" part.

Nice job on this, good performances.
