I do. I find the articles on the LifeTeen site to be often times inspiring and exciting. I like to see our youth rallied and pumped up.
With that said, I think it is important to view LifeTeen as a stepping stone meant to lead you into a life of prayer. When all of the excitement of LifeTeen is stripped away and you are left alone as an adult between just you and Jesus in the Eucharist, you need to be able to worship just as fully as you did with the fire and passion if youth. I have known some to be involved in the LifeTeen program that have used it as a crutch in adulthood, leading to misuse of liturgy and the inability to worship in a traditional Mass. I myself am the product of LifeTeen. I gave 13 years of my life to leading a LifeTeen band. I think it is a great tool that is not intended to be life long. That’s just my opinion.
Edit: I missed the fact that you are not a teenager. Sorry about that oversight. I think the same rules apply even in adulthood, if this is what is bringing you back to the Church. Let it bring you back, let it inspire your questions and your passions and that burning, exciting love for Jesus. But I personally encourage you to take the excitement and the passion and the fire it helped to kindle and apply it to your prayer life so that you are still able to fully worship even after the music and the excitement is gone. Because the Mass is not about the music or the excitement, as *some * (some, not all) LifeTeen programs unfortunately make it out to be. It is about the crucified Christ who is bleeding and weeping for us all.
