There are lots of songs which appear to be inspired by Robert Johnson's song Cross Road Blues aka Crossroads:

Find song partial lyrics

That is one of a few sites I found where partial song lyrics can be used to search for a song.

Approximately 100 songs showed up in the results but many were repeated entries, either performed by the same person or band, or a version of a specific song by a different performer or band so at a rough guess there may be 20 or more different songs with the words "crossroads", "sell" and "soul". (In my opinion, that is a great tribute to Johnson's original song.)

To complicate the search, some of the songs have been performed by different singers or bands, so they are the same song but different performances. The song you are searching for may also have been performed by a male singer or a band so narrowing the search to a female performer may mean you miss the song you are looking for.

Perhaps you could look through the songs which showed up on the link I posted and see if you recognise the song or get some sort of lead towards the song you want to find.
