'Glee' has a diverse lineup of songs planned for next Tuesday's midseason finale, 'On My Way.' The episode features six tracks, including the current No. 1 song in the country, Kelly Clarkson's 'Stronger (What Doesn't Kill You).'

'On My Way' showcases the Regionals battle, so the Warblers and New Directions both bring their best energy on multiple performance numbers. Brittany, Santana and Mercedes are spotlighted on 'Stronger.' Rachel sings 'Here's to Us,' a mid-tempo tune by hard rock act Halestorm, while Blaine takes on 'Cough Syrup' by indie rock favorites Young the Giant.

The latest 'Glee' mashup merges modern hip-hop with '90s R&B in a medley of 'Fly' by Nicki Minaj featuring Rihanna and 'I Believe I Can Fly' by R. Kelly. Rachel, Artie, Santana and Blaine all take turns in the lead on the 'Fly' mashup.

Sebastian and the Warblers offer their rendition of Lenny Kravitz's catchy rock song 'Stand' and the Wanted's 'Glad You Came.' The Warblers add impressive harmonies to Kravitz's track, which could work in their favor as they attempt to dethrone the New Directions and advance to Nationals.

'On My Way' airs on FOX on Tuesday, Feb. 21, and will be the last new episode of the series until the show returns from hiatus on April 10.
