My musical taste/s haven't shifted so much, but of late i've been into some dance tracks, with the latest being "Champion" by Chipmunk feat Chris Brown.
I think that Brown's effort at rap is good, even though he sounds like Kanye "Rest", but that didn't spoil the song, not only because he maintains some individuality in his effort, butr also because the song in itself is too strong.
Check it out.
