looking for midi info and chord progressions
 

Hi. I'm looking for 2 things regarding music. If you know only one, that'll help too.

1. Are there any websites that have midi files of popular songs and artists for download?

2. Are there any websites or books that displays just the key and chord progressions of popular songs and artists (such as I-V-vi-IV.....)? I'm not looking for sheet music or musical scores (no measures, bars, staffs). I'm looking for just chord progressions.

Thanks
