Thats incredibly thoughtful of you to go back to give credit to the artist. If you have the name of the artist and/or track title then yes, I encourage you to search for them on SoundCloud as well as in a general browser search. Just be aware that if you do find a match on SoundCloud you may want to go the extra step and message the creator to make sure it is indeed the artist and not another user using the same name.
Best of luck and please let me know if you have any further questions.
