Same goes for me - in my teens and early twenties, I listened to plenty of music with lyrics while working. By the time I got into my mid/late twenties, that changed. Now I more or less exclusively listen to electronic music (jungle / dnb / downtempo / idm).

Music helps me get into a flow, but it has to be pure vibe and rhythm. Lyrics definitely distract from the task. Family and peers find it odd that I don't really listen to or seek out music with lyrics.

I can enjoy it, just not what stimulates me at this point.
