A Suggestion - I might not have entertained it if i had to implement it myself.
Rating for the songs 5-1. 5 being highest. The Leaders and followers too have a taste for good songs. Now would it be feasible to have an additional feature which will build on Search and provide a facility for rating.
For e.g. I search Kishore Kumar and lata Mangeshkar and rate the songs listed . Similarly others may rate songs as per their search and whichever songs they want too. On Search - the songs with Higher Ratings get listed on top. Over a period of time this may give good results
