style123, much has been written and said about this topic by people here and teachers and rebbes alike.
Here is what I know to be true: 1) there was a gezira against listening to any live music after churbun habayis which may no longer apply today especially with jewish lyric songs. 2) songs with lyrics which are provocative or immoral are obviously wrong to listen to just like any other provocative or immoral speech. would you sit with a friend and use bad language and talk about lowlife activities? no! so why listen to it on the radio? 3) finally, putting lyrics aside, there is NO SUCH THING as music which is Jewish and music which is not Jewish. ALL music. Ever. In the history of mankind. always. was based on all the music that existed prior to that time and which influenced the artist. There is literally not a single song you have every heard in your life which was not influenced by nonjewish music. reversed: every song you have ever heard was influenced by nonjewish music. Every Jewish song you have ever heard was either a direct rip off of not jewish music (like avraham fried and mordechai ben david) or was heavily influenced by not jewish music like chazzunus. so if you hold the churban ban no longer applies and the lyrics are not trief and you find beauty in the song it is my humble opinion that you have an obligation to listen to it – jewish or not – and that depriving yourself of such music makes you a lesser human being.
