"i got hundred dollar bills (in my pocket)" song
Sorry I don't have alot of information because I heard it in a store and didn't think to record it!
It's a kind of lo-fi/bedroom pop type song and there was a lyric along the lines of "i got a hundred dollar bills". The singer was female singing in a soft voice
The closest example I can think of genre wise is this song. I heard it in a spiritual healing store (rocks, incense, etc) if that gives you any idea of what it may be.
