Will 'Empire' Mean meer To The muziek Industry Than 'Glee'? 

Fox’s new hit series bet big on original music — and is starting to take over the Hot 100. How will that help its musical legacy in the long run?

\'s timing, like Cookie Lyon\'s wardrobe, couldn\'t be more impeccable.

Following its January debut, the hip-hop soap opera starring Terrence Howard and Taraji P. Henson continues to hit ratings highs for Fox over the same stretch of winter in which

cast set the record for the most appearances on the Hot 100 in the chart\'s 55-year-plus history, and notched Top 10 placements with covers of Journey\'s "Don\'t Stop Believin\'" and Katy Perry\'s "Teenage Dream," thanks to a strategy of releasing multiple tracks digitally with each new episode. The

compilation albums were also tremendous sellers, with two full-lengths (

was a pop culture tidal wave that was suspended in mid-air from roughly 2009 to 2011, before predictably crashing down in recent years.

For all the "Wait, Cookie said WHAT?!" tweets that have been fired off in recent weeks (and will be fired off in the years to come),

\'s all-genres-included approach. Still, there\'s a chance that

simply because of one key difference between the shows: the decision to rely on original music instead of cover material.

\'s albums and track sales were based on familiar songs, performed by a high school Glee club millions of viewers grew to love and made available on iTunes as each episode\'s credits rolled (the original track "Loser Like Me" did peak at No. 6 on the Hot 100 in 2011, but proved to be a flash-in-the-pan chart hit). The commercial success of new renditions of songs from the spectrum of mainstream music, from Cee Lo to Lady Gaga to Fun., called back to another era of pop in which cover songs were a permissible method of chart dominance. And hey, who doesn\'t enjoy classic songs, from "Proud Mary" to "I\'ll Stand By You" to "Imagine," being brought back into popular culture thanks to updated versions the tweens can get behind?

A lot of those covers were memorable. But how many actually lasted long after their television debuts? The nature of the weekly series kept fans wanting the newest songs on their iPod, so music sales for older episodes quickly dried up. The longest run by a

songs appeared, came from their take on "Don\'t Stop Believin\'," which lasted for only seven weeks on the chart. The large majority of these cover songs acted like shooting stars -- cracking the Hot 100 made for a spectacular achievement, but you\'d miss it on the chart if you blinked.

is doing that now, too -- a season 1 compilation was released on Tuesday, and it\'s aiming for the top of next week\'s Billboard 200 albums chart.

\'s early tunes, and hasn\'t had any songs infiltrating the top of the charts. But it\'s getting closer to making real chart moves -- and with original tracks courtesy of executive music producer Timbaland. Instead of saddling its characters with a string of hip-hop covers, the concept of the show calls for absorbing music that helps define its heroes. And after weeks of buildup and plot development, those songs are finally connecting. Timbaland\'s importance in

\'s overall success cannot be overstated -- as ridiculous as some of the plot points have been (the mid-day pistol showdown with Judd Nelson!), the music has always felt authentic, and the newest songs sound like they could feasibly work at radio.

After a string of songs cracked the low end of the Hot R&B/Hip-Hop Songs chart, "Keep Your Money" became the Empire Cast\'s first song to appear on the Hot 100 chart, peaking at No. 99 in February. Last week, "You\'re So Beautiful" debuted at No. 71 last week with 55,000 downloads sold, according to Nielsen Music, and on this week\'s chart, "Conqueror" starts at No. 42. The debuts are going higher and higher as the show\'s audience grows, but

\'s musical output is also improving: after a handful of good-but-not-great rap and R&B tracks were featured on the show ("Good Enough," "No Apologies" and the aforementioned "Drip Drop" included), the catchy, soulful "You\'re So Beautiful" sounded like a proper breakthrough track, and "Conqueror," featuring guest star Estelle, made for the show\'s best ballad to date.

Perhaps most impressively, the older songs are starting to stick around: "You\'re So Beautiful" actually climbs on this week\'s Hot 100, moving up 24 spots to No. 47, and earns this week\'s top Digital Gainer honor. The song appeared in back-to-back episodes of

music\'s growth at this point, but crucially, the show is slowly establishing the radio-ready stars behind their original tunes. Jussie Smollett, who plays the R&B outsider Jamal on the show, is clearly the breakout, a likable personality with a booming voice that anchors "You\'re So Beautiful" and gamely duets with Estelle on "Conqueror." Although he\'s still largely known for his character on

, which hasn\'t produced any crossover stars out of the singer-actors delivering those mega-selling covers. There\'s a variety of reasons why the

kids have yet to take off on their own -- Lea Michele\'s solo album lacked a hit single, Darren Criss\' music is still in the works, Naya Rivera hasn\'t developed a distinctive sound yet -- but the biggest one is that

didn\'t give its artists as much of an opportunity to individually shine because of its covers-first format. Love Lea Michele\'s voice? You had to hear it sing other artists\' words for years before she could find the time to commit to finishing a solo album. That\'s what happens when a singer like Michele is tied to shooting and promoting a smash television series for multiple seasons -- original music understandably hops on the back burner. Smollett has made the same commitment to

: he might become a star with hand-selected tracks that fit into a narrative arc, but those songs likely come closer to capturing his artistry than any classic cover could.

, and Fox\'s new smash may never be as innovative to the industry as its soon-to-be-gone predecessor. Yet it will be interesting to see how high

can grow off of Glee\'s foundation, while pushing digital product that is previously unfamiliar but immediately compelling.

a blueprint of sorts for cross-platform domination -- it\'s time to see how far
