Music to Impress my Kid's Friends?

Lately, my college aged children have been bringing friends over to here my system and I would love to buy a few great sounding cds that are currently popular. I obviously have lots of quality music to play but it might have more impact on the kids if they were more familiar with the music. I bought the Adele cd thinking that might do the trick but was I wrong. I'd even invest in some current vinyl if I knew they would were outstanding from a recording standpoint. Thanks
