Just in time for tonight's (Feb. 25) episode of 'Glee,' you can get a sneak peek at what to expect from the musical numbers.

Appropriately titled 'Frenemies,' the episode centers around conflicts between roomies Rachel and Santana, as well as Tina and Artie. We previewed each of the tracks from the episode and can say that fans are totally in for a treat.

Check out the tracklist -- and our reactions! -- below.

'Whenever I Call You Friend '(Kenny Loggins & Stevie Nicks) - Artie & Tina

This 1978 track isn't from the usual 'Glee' repertoire, but we love that Artie and Tina totally own it. The duet is a slam dunk for this episode, which explores the possibility that there is limits to friendship.

'Brave' (Sara Bareilles) - Santana & Rachel

Sara Bareilles is all about empowering anthems, so we love that two of our fave 'Glee' stars teamed up to cover 'Brave.' Santana and Rachel's voices blend together so well, encouraging listeners (and each other) to summon up a little extra courage.

'My Lovin' (You're Never Gonna Get It)' (En Vogue) - Artie & Tina

Performances like this hip-hop track are what make 'Glee' so great. It's a classic, it's an unconventional choice -- and it shows off what the cast can do. We dare you to resist tapping your toes to this crazy-catchy cover.

'Don't Rain on My Parade' (From 'Funny Girl') - Santana

Rachel may be known for her love (aka obsession) with Barbra Streisand, but we love that Santana took on this iconic track. The song is especially perfect since the episode focuses on Rachel and Santana's roles in 'Funny Girl.'

'I Believe in a Thing Called Love' (The Darkness) - Kurt & Elliott

This rock anthem brings out an amazing side of Kurt and Elliott. The guys definitely give it a Broadway-esque spin, but they still maintain the powerful sound of the song. Yep, we're definitely nodding our heads to this number.

'Every Breath You Take' (The Police) - Rachel & Santana

This classic by the Police is catchy in its own right, but Rachel and Santana add their own flair to it. The two ladies totally belt out the chorus like only they can. It's Sting meets Broadway, and it's total perfection.

'Breakaway' (Kelly Clarkson) – Blaine, Artie & Tina   

It's not easy to take on a Kelly Clarkson hit, but this trio totally nails it. We love, love, love Kelly's original version, but Blaine, Artie and Tina harmonize the heck out of this cover. It's not an obvious choice for 'Glee,' but it's really-well done.
