Display BPM and Key for Generated Songs

Description: It would be helpful if Songer displayed the BPM (tempo) and key for every generated song. This would make it much easier for musicians, producers, and performers to: Recreate songs in a DAW Perform songs live with a click track Remix or arrange tracks Collaborate with other musicians Match songs to other tracks by key and tempo Ideally, the BPM and key would be shown on the song details page and included with downloaded files. An automatic BPM/key analysis for existing songs would also be a great addition. This would save users from relying on third-party tools to analyze their songs after downloading them.
