So I asked Taxi and, as always, got a prompt and cheerful reply... It is SONGS WITH VOCALS ONLY... NO INSTRUMENTALS. Thank you again, Anthony @ Taxi!

Lyrically, your SONG can have any of the following themes: PARTYING, GOING OUT, HAVING FUN, GET READY, GOING CRAZY, BEING WILD, etc. Male or female vocals are BOTH ok. MUST be CURRENT sounding! No "synthy" sounding SYNTHS or obvious DRUM MACHINES. They need the instruments to sound organic and real, not stiff-sounding MIDI tracks!! The estimated fee for this placement is $15,000 minus 30% of the licensing fee. You must own or control 100% of the Master and Composition rights. NO artist or song SAMPLES allowed for this pitch. You will keep 100% of your master, publishing and writer's share! Broadcast Quality is needed (excellent home recordings are fine.) All submissions will be screened on a YES/NO BASIS by a person they've hand-picked. NO CRITIQUES FROM TAXI. ALL submissions must be received no later than 11am (PST) Monday, January 16th, 2012 TAXI # Y120116RK
