Following Lady Gaga's four-week win with 'Do What U Want' (putting her and the song in the Pop Clash Hall of Fame), PopCrush is closing out the year with a new Pop Clash between two beloved TV stars with amazing and unique voices. Lea Michele, aka 'Glee' heroine Rachel Berry, is rocking solo single 'Cannonball,' while former 'High School Musical' vixen Ashley Tisdale, who played Sharpay Evans to perfection, returned to music when she penned an emotional new tribute to her grandfather, 'You're Always Here.'

Michele, who also recently dropped a new song called 'Battlefield,' shows off the depth and range of her voice with 'Cannonball.' We're so used to her singing covers of songs we know and love on Fox every week, so to hear the gorgeous star deliver the words and the melody of a song we don't know is new and fresh. Michele infuses the song with pure power when she sings "I think I found the light at the end of the tunnel" and "I gotta get out, gotta get out, gotta get out."She has lit the fuse of her solo, post-'Glee' career with 'Cannonball.'

Tisdale dropped her new song a few weeks ago, dedicating it to her late grandfather. She worked on the song with her fiance, Christopher French, so it's incredibly personal for her on multiple levels. It's an ode to someone she loves and misses, co-created by someone she is planning on spending the rest of her life with. She's not the vocal belter that Michele is, but the song is emotionally resonant and super catchy -- and it's about a subject we can all relate to. It's a sweeping pop song that reminds us how much we missed the Tiz's voice.

It's up to you to decide which TV diva reigns supreme with her new song: Lea Michele or Ashley Tisdale. Vote once an hour until the polls close at 3PM ET on Jan. 6.
