 The pair of performances by the McKinley High God Squad , however , received rather more attention . The first , " Stereo Hearts " , received a trio of " B − " grades from reviewers : Chaney said it was " a bit much " but " semi @-@ enjoyable " , Slezak described it as a " somewhat bland rendition " , and Lynch wrote that " Joe Hart 's vocal debut on Glee proper was fine , but Sam 's rapping was not " . Bell said " Mercedes was flawless " and then called the song 's rapping " one major flaw " , but Futterman wrote that " Sam wins for most surprising Glee vocalist by convincingly taking on Travie McCoy 's rap " . Flandez said that the " voices melded well together " . The " Cherish " mash @-@ up was better received , and garnered grades from " B " up to " A − " , the highest from Slezak , who deemed it a " delicious " dessert . Lynch said " Quinn sounded great " with his " B " grade , and Chaney 's " peppy , sweet number " was attached to a " B + " . Flandez called it a " cute mashup " , and VanDerWerff said the rendition was " nice and understated " .
