No, gaga doesn't discriminate against other labels. She promotes the hell out of semi precious weapons and they just got signed to epic records. She also promoted an underground band before called 'we are the world' who wasn't on Interscope. If she likes something she's gonna make it known regardless of the labels.

It's not always about Britney, now is it?

Now, Lem; I know you aren't always this messy, but get yourself together, sis.

Gaga has always supported the "industry" and has made attempts to ensure people actually purchase music (and to enjoy it) through her own unique promotion (co-branding, co-marketing, developing a strong sense of brand). That being said, it's definitely a record label effort too, but it doesn't work without the right kind of artist, and Gaga is one of those.
