help me with my class?

This is all great, thank you all so much and please keep them coming!

Even if I don't teach my music class anymore, I can still include musical topics as sample research topics for us to use for in-class practice. Today, among two other nonmusical topics, I presented my first year (""traditional"") college students with the question of (basically, not in these exact words) "what was going on in 2012 to produce a Billboard Hot 100 that looks like this[displays list of songs]??"

They loved it! They kept going down the list and being shocked over and over like "and this one?" etc until I saw them looking up other lists of music from 2012 and continuing to be shocked that 1) it was 10 years ago and 2) they still liked a large proportion of the songs. Wednesday they will present me with their theories. Fun topic I've been thinking about and finally implemented today.

My observations:
they love CRJ, knew she had a new album out, a couple were legit fans
"Someone That I Used to Know" was so beloved by one of them that she had it downloaded to her phone for anytime listening
it was enjoyable to see the passage of time sink in as they realized how different the world seems than it did in 2012
overall good topic, would float again maybe with tweaks as time passes (as it does)
