Sweet & sour

I have a friend, she's been a good friend of mine for some time says she has a friend who's falling for me she likes the way I rhyme my word and in the end my best friend says she wants a piece of me...

You're tone deaf but you're singing a song You feel lost but you know where you're from You're not pretty but you got it going on Your head swims in electric blues If all fails, you can't lose You lie...
